1.The strains of the rust citron(cocoa) red and white egg are types of natural mutation in our laboratory.2.The citron egg genes in our laboratory and cocoa egg genes in Japan are different genes and different chromsomes.3.The colour of the rust egg is as yellow the stem of dry rice straw.The serosa is the main pigment of rust.The colour of the compound eyes of adult are red.The genotype is ru/ru re/re +~(w5)/+~(w5).4.The colour of the red egg is red.The genotype is+ru/+ru re/re+~(w5)/+~(w5).5.The colour of the citron egg is cocoa colour,and the colour of the compound eyes are still the cocoa colour.The genotype is +re/+re ru/ru+~(w5)/+~(w5).6.The serosa of white egg is colourless,its egg-yolk goes through the egg shell only.So it is light yellow.The genotype is ru/ru re/re w_5/w_5.But white egg gene we is epistasis on citron egg gene ru/ru +r~e/+r~e and red egg gene re/re +ru/+ru.7.When citron egg strain crosses with red egg strain or rust egg strain crosses with normal one,all of the F_1 eggs show the black colour only.The F_2 are segregated into black egg,citron egg,red egg and rust egg in the ratio of 9:3:3:1.When the F_1 with black eggbackcrosses rust egg strain,the RF_1 expresses black egg,citron egg,red egg,rust egg in the ratio of 1:1:1:1,when the F_1 with black egg backcrosses citron egg strain,they produce black and citron egg,in the ratio of 1:1;When the F_1 backcrosses red egg strain,they produce black and red,in the ratio of l:1.8.As the citron egg strain crosses with rust egg strain,the F_1 expresses citron egg,the F_2 produce citron egg and rust egg in the ratio of 3:1. When the F_1 backcrosses the rust egg strain,RF_1 are segregated into citron egg,rust egg in the ratio of 1:1.9.According to the experimental results,the authors suppose that the gene of rust egg is ru,red egg is re and white-5 is w_5,three pairs of normal genes are +~(ru) +~(re) +~(w5) and they are considered as complementary genes and epistatic-hypostatic genes.All of the above experiments may be explainable all as follows:A.Rust egg gene ru complementation with +~(re) express citron egg in genotype ru/ru +~(re)/+~(re).B.The complementation of the Red egg gene re with +~(rn) expresses red egg,their genotype is +~(ru)/+~(rn) re/re.C.The complementation of +~(ru) with +~(re) togather produces black egg in genotype +~(ru)/+~(ru) +~(re)/+~(re).D.The gene ru is epistasis on re,viz.When both ru and re are in the same individuals,their genotype ru/ru re/re rust egg appears only,red egg doesn't appear.10.The authors aslo observed that the white-5,w_5 is epistasis on rust egg ru and red egg re.Their genotype is w_5/w_5 re/re +~(ru)/+~(ru),of which the white egg appears only,the red egg doesn't appear;but in w_5/w_5 ru/ru +~(re)/+~(re),the white egg appears only,the citron egg does not appear.11.In the F_1 and F_2 with that rust egg strain (ru/ru re/re) crossing with red egg strain(+~(ru)/+~(ru) re/re)and between +~(ru) complementary gene of re and re its,people often have a mistaken idea that is they consider is due to re the segregation.in fact,it is the segregation of the complementary gene +~(ru).12.The gene +~(ru) is dominace to the ru and complement to the red genere,this is expressed pleiotropy of the gene +~(ru).

1.锈色卵、橙色卵、红色卵、白色卵系统均属西南农业大学家蚕遗传研究室的自然突变型.2.上述基因除已发表的以外,本实验进行全面的观察,而以锈色卵及橙色卵为主,遍及红色卵及白色卵的关系,均在1983~85年进行.3.我室的橙色卵基因和日本的赤褐卵,系在不同染色体上各别的基因.4.锈卵的卵色为近似于干稻草杆的锈黄色.浆液膜以黄锈色素为主,稍近似褐色,成虫复眼红色与红卵蛾一致,基因型为ru/ru,re/re,+~(w5)/+~(w5).5.橙色卵的卵色为可可色,产下的卵,在转色初期,浆液膜有明显红色素,尔后逐渐成为深红色,比黑色卵遥紫,近于藤色,终成可可色(cocoa),成虫复眼也是可可色,基因型为ru/ru、+~(re)/+~(re)、+~(w5)/+~(w5).6.红色卵的卵色为红色,基因型为+~(ru)/+~ru、re/re、+~(w5)/+~(w5).7.白色卵浆液膜无色只有卵黄色透过卵壳,故呈淡黄色,普通称之为白色卵.基因型为ru/ru、re/re、w_5/w_5,但白卵基因w_5对橙色卵基因ru/ru、+~(re)/+~(re)及红色卵基因re/re,+~(...

1.锈色卵、橙色卵、红色卵、白色卵系统均属西南农业大学家蚕遗传研究室的自然突变型.2.上述基因除已发表的以外,本实验进行全面的观察,而以锈色卵及橙色卵为主,遍及红色卵及白色卵的关系,均在1983~85年进行.3.我室的橙色卵基因和日本的赤褐卵,系在不同染色体上各别的基因.4.锈卵的卵色为近似于干稻草杆的锈黄色.浆液膜以黄锈色素为主,稍近似褐色,成虫复眼红色与红卵蛾一致,基因型为ru/ru,re/re,+~(w5)/+~(w5).5.橙色卵的卵色为可可色,产下的卵,在转色初期,浆液膜有明显红色素,尔后逐渐成为深红色,比黑色卵遥紫,近于藤色,终成可可色(cocoa),成虫复眼也是可可色,基因型为ru/ru、+~(re)/+~(re)、+~(w5)/+~(w5).6.红色卵的卵色为红色,基因型为+~(ru)/+~ru、re/re、+~(w5)/+~(w5).7.白色卵浆液膜无色只有卵黄色透过卵壳,故呈淡黄色,普通称之为白色卵.基因型为ru/ru、re/re、w_5/w_5,但白卵基因w_5对橙色卵基因ru/ru、+~(re)/+~(re)及红色卵基因re/re,+~(re)/+~(re)均为上位.8.橙色卵系交红色卵系的F_1或锈色卵交正常卵的F_1均为黑色,F_2均分离黑色、橙色、红色、锈色四种成9∶3∶3∶1之比,以F_1黑色卵系回交锈色卵生黑、橙、锈、红四种成1∶1∶1∶1之比,回交橙色卵生黑,橙成1∶1之比,回交红色卵黑红成1∶1之比.9.橙色卵交配锈色卵第一代F_1为橙色卵,第二代F_2生橙锈成3∶1.将其F_1回交锈色卵RF_1生橙锈成1∶1之比.10.设锈色卵基因ru红色卵基因re及第5白卵基因w_5及其各个的正常基因+~(ru)?三对基因,其中第一,ru与re两对基因存有互助基因的关系,第二,w_5在ru及re的上位,而ru在re的上位,则所有实验成绩的结果均可说明.A.锈色卵基因ru与+~(re)互助成橙色卵,基因型为ru/ru、+~(re)/+~(re);B.红色卵基因re与+ru助成红色卵,其基因型为re/re、+~(ru)/+~(ru);C.+~(ru)与+~(re)互助成黑卵,其基因型为+~(ru)/+~(ru)、+~(re)/+~(re);D.ru在re的上位,故ru与re共存时的ru/ru,re/re基因型,只现锈色卵ru的锈色而不现红色卵基因re的红色.11.第5白卵基因w_5在锈色卵及红色卵的上位,故此两者共存时则均只发现白色卵而不发现锈色卵及红色卵.故在w_5/w_5,re/re、+~(ru)/+~ru基因型只发现白色卵不发现红色卵,在w_5/w_5,ru/ru,+~(re)/~(re)基因型也只发现白色卵而不发现橙色卵.12.由于锈色卵基因ru及其正常基即+~(ru)与红色卵基因re及其正常基因+~(re),两对基因是互助基因,而由于互助基因间的结合与分离,往往会误认为本来卵色间的分离颠倒了显性和隐性关系.例如锈色卵和红色卵交杂F_1为红色卵,F_2分离红锈成3∶1,很像红对锈是显性,但实际红色卵基因型+~ru/+~(ru)、re/re,锈色卵基因型为ru/ru、re/re,两者F_1,+~(ru)/~ru、re/re,其F_1异质性是+~(ru)/ru,虽现红色卵,但并不是红色卵re/re的自身re能发现红色(因re如无+~(ru)即不能发现),而是因为有+~(ru),此基因型才发现红色,当F_1++~(ru)/ru互交形成F_2个体时,则成ru/ru,+~(ru)/+~ru或+~(ru)/ru,而在+~(ru)/+~ru、re/re或+~(ru)/ru、re/re基因型虽仍形成红色,但当ru为同质性,成ru/ru、re/re基因型时,则红色即不发现,而让位给其上位基因ru/ru,发现锈色卵.所以,此锈色卵的不发现并不是因为它对红色卵是隐性,而是因为ru对其正常(normal)+~(re)是隐性的缘故;恰恰相反,自其本质来说,红色基因re本身对锈色基因ru,反而是隐性,就是下位,而绝不是显性.13.利用锈色卵与红色卵两对基因为材料,可以按需要作成3∶1,9∶3∶3∶1及9∶3∶4的遗传分离比供给遗传学的实验材料.只要饲养几个蛾区,即可互相交杂获得100~200个卵区,每区有400-500卵,完全可以计数足够的遗传分离比,这是最便宜的实验教学材料.

1. when rust egg straincross with white egg (w_2) strain, all of the F_1 egg appear normal black colour. The F_2 egg are segregated into black egg, orange egg, red egg, rust, egg, white egg in the ratio of 27: 9: 9: 3: 16。 2. when the F_1 in rust egg cross with white egg strain backc- rossed rust egg strain, four kinds of egg colours black egg, orange egg, red egg, rust egg in ratio of 1: 1: 1: 1 are obtained through reciprocal cross.

1. when rust egg straincross with white egg (w_2) strain, all of the F_1 egg appear normal black colour. The F_2 egg are segregated into black egg, orange egg, red egg, rust, egg, white egg in the ratio of 27: 9: 9: 3: 16。 2. when the F_1 in rust egg cross with white egg strain backc- rossed rust egg strain, four kinds of egg colours black egg, orange egg, red egg, rust egg in ratio of 1: 1: 1: 1 are obtained through reciprocal cross. After the F_1 backcrossed white egg, orange egg and red egg strain, the RF_1 eggs produced black egg and white egg, black egg and orange egg, black egg and red egg, separately, in the ratio of 1: 1。 3. Author observed that the gene of white-2 wg is epistasis on the Just egg, ru and red egg, re. As a result, in the gene types of ru/ru, +~(re)/+~(re), w_2/w_2; +(ru)/+(ru), re/re, w_2/w_2 and ru/ru, re/re, w_2/w_2, the phenotype of white egg is shown only。 4. In the light of the these results, auther supposes that the gene type of rust egg is ru/ru, re/re, +~(w2)/+~(w2); orange egg is ru/ru, +~r(?)/+~(re), +~(w2)/~(w2); and red egg is +~(ru)/+(ru), re/re. +~(w2)/+~(w2)。All of above experiment may be explained at all。 5. This present is evident that the gene of ru is not on the 5th and 10th chromsome in silkworm, just the same as the result of preceding paper。The complementation of the gene ru and+~(re) produced the orange egg, white re and +~(ru) appeared red egg。 Also auther surxeyed that ru is epistasis on re, ViZ。when the both ru and the re:ru/ru, re/re, are in the same individuals, the rust egg appears only, the red egg doesn t appear。

1. The aplicat-yellow-egg we used in this experiment, is a new strain. in Silkworm, Bombyx mori. The gene was named apy. 2. The aplicat-egg gene, apy is mixed types of Mendelian and maternal inheritance. The F_1 is similar to its parent famale in egg colour. This is a maternal inheritance. Whereas in F_2 segregation occurs a single batch vith a ratio of three normal dark to one aplicat, it is a mendalian inheritance as well. Thus, The aplicat geneis a mixed maternal inheritance. 3. The strain females of the aplicat egg, apy crossed with the red egg strain males. The F_(?) egg colour is aplicat and is similar to its famale parent. In the reciprocal, the egg colour is normal dark. But both the F_2 segegated into dark, red, aplicat egg with the ratio in 9:3:4. This accords the ratio of mendelian inheritance. Thus we deduced that the gene of aplicat-egg, apy was epistatic on the red gene, re. 4. The aplicat egg contained a large number of kynurenine before its pigments formed. After that time. the eggs processed the dormancy and then were out of coldstorage by the next spring. The kynurenine was still nexst at that moment 5. When various Pigment was carriecl out by the sephader column chromatography, the normal type, dark egg had moat band, amount of five kinds. From the botttom of the column to the top, there was ocher, orange, pink, blue-purple, light-yellow rerpectiely. Other mutant types had three bands. From the nottom of the column to the top, respectively, the aplicat-egg had ocher, orange, and yellov. The red-egg had ocher, orange, and red. The rust egg had ocher, orange, and pink. The cocoa(citrone)egghad ocher, orange and blue-purple. Among of them, the ocher and the orange bands are common in all experimental eggs, show in Fig. 3, 6. Chromatography the pigments was caried out with five colour in eggs, the normal, the aplicat, the red, the rust, and the cocoa. At the lowest band of each column, there was ocher band only. But the width of these bands and volumns were different each other. For their absorbtion spectrum curv were similar, it is clear that they contained the same elements. 7. From the bottom of the column to the upward, the second band was orange, the width of them was different each other, the band, which were produced by the aplicat-egg and the rust-egg were the width. They were about two times as wide as that of normal egg. The width of red egg is less, but it is wider than thus of normal. The patterns of scanning record cruve were identical on the five colour eggs. We learnt that they consisted of same subtance(Fig. 2). 8. The thirdy bands were-different each other in the mutants, They were light yollow, red, pink, and blue-purple band for the apliat, the red, the rust and the cocoa(citron) egg respectively. 9. According to the results, It was quite evident that the gene of normal standard egg colour was not individual, in faet, it contains five kinds of gene, +~(oc)+(or)+(Pu)+(Pi)+(ly) at least, they formed a multigene family. 10. For the same reason, the gene of the aplicat egg must be a multigene family, consisting of+(oc)+(or) and apy. The gene of red egg must be a multigene family consisting of+(oc)+(or) and re. The gene of rust egg must be multigene family consisting of+~(oc)+~(or) and ru. the gen of cocoa egg must multigen family consisting of +(oc)+(or) and pu. 11. during the process of egg pigments producing, at the serosa the enzyme Ⅲ, that turned kynurenine to 3-kydroxyhnurenine is very scanty.
