    The phenomenon of dominant and segregation of hybrids is of essential importance ingenetics.What is the rule which governs this phenomenon? According to Morganists thisphenomenon is controlled by the behavior of genes,while the Michurinists took it as the resultof mutual assimination of the germ cells of two parents.More than sixty years ago,genetists could not determine exactly how many genes are in-volved in a quantitative character,nor chould they demonstrate how the genes react.Al-though there are many theories to explain this genetical phenomenon,yet it seems that noneof them is able to give a general explanation for dominance and segregation of hybrids.The aim of this paper is to analyze,mathematically the phenomenon of dominance andsegregation of hybrids in a new theory,that the average measurements of one character of thehybrids are determined by the relative intensity of heritability of the two parents withoutconsidering how many pairs of genes,or how the genes effect the character.Under certain conditions,the phenotypic expression is determined by two factors:one isthe relative intensity of heritability of two parents,and the other is the average measurementsof their characters.Besides,the nature of transmission of genetical materials to their pro-genies is also significant to the phenotypic expression of the hybrids.According to a numberof genetical data,the action of inheritance between parents and hybrids may be either arith-metical or geometrical.If we take a_1 and a_2 as the relative heritability of two parents and.P_1 and P_2 as theiraverage measuremenst of a given character,then the measurement of the character of theirhybrids will be:(i)in arithmetical relationF_1=P_1a_1+P_2a_2 (1)(ii)in geometrical relationF_1=P_1a_1.P_2a_2or lnF_1=a_1lnP_1+a_2lna_2 (2)in which a_1+a_2=1.By formulae(1)and(2),we may explain many types of genetical data in one formin which should be explained separately in the theory of genes,such as,genes of independentassortment,several types of factors interaction,and others.Other rules may also be derived from formulae(1)anh(2)as follows:Ⅰ.When the relative heritability of two parents is equal,then we have(i) in arithmetical relationF_1=1/2(P_1+P_2) (3)(ii)in geometrical relationF_1=(P_1P_2)~(1/2) or lnF_1=1/2(lnP_1+lnP_2) (4)Ⅱ.When the measurements of a character of parents and hybrids are known,we maycalculate the relative heritability of two parents by formulae(1)and(2),i.e.(i)in arithmetical relationa_1=(F_1-P_2)/(P_1-P_2) (5)and a_2=(P_1-F_1)/(P_1-P_2) (6)in which the value of a_2 is coincident with the“degree of dominance”derived by Zeleny(1920)in another way,and is equivalent to the“hybrid index”of Hubbs(see Riley,1948).(ii) in geometrical relationa_1=(lnF_1/P_2)/(lnP_1/P_2) (7)and a_2=(lnP_1/F_1)/(lnP_1/P_2) (8)Ⅲ.When the relative heritability of two parents is equal,and when the hybrids areselfed or backcrossed with their parent,then the measurement of a given character of pro-genies in second generation will be:(i) in arithmetical relation(?)(9)(ii)in geometrical relation(?)(10)These formulae are more fitting than those derived by Wright(see Power,1942)Ⅳ.When the hybrids are selfed or backcrossed for n-l generaations,the average measure-ments of a given character of progenies(no selection)will be:(i) in arithmetical relation(?)(11)Where Pr is the average measurement of the recurrent parent.The measurement of F_nis coincident with the result of Burdick(1956).(ii) in geometrical relationF_n=F_1B_n=P_r(2~(n-1))/(2n).P1/(2~n) (12)All the above mentioned equations have been proofed in theory and in practice.

    It has been already established that the person with erythrocyte glucose-6-phosphate dehydrogenase deficiency is liable to develop favism. It is generally accepted that the heterozygote does not develop the disease. In order to detect heterozy-got.es, the writer has used three methods (namely MR-microhistochemical elution test, MR-mierophotometric test, and glutathione stability test), and found that the MR-microhistochemical elution test is most sensitive, detecting heterozygotes in 92%.

    It has been already established that the person with erythrocyte glucose-6-phosphate dehydrogenase deficiency is liable to develop favism. It is generally accepted that the heterozygote does not develop the disease. In order to detect heterozy-got.es, the writer has used three methods (namely MR-microhistochemical elution test, MR-mierophotometric test, and glutathione stability test), and found that the MR-microhistochemical elution test is most sensitive, detecting heterozygotes in 92%. Moreover, there are 17 females with history of favism 10 out of 17 females with history of favism are found to be heterozygotes. This indicates clearly that heterozygotes are liable to suffer the disease after ingestion of fava beans.In addition, according to the degree of expressivity shown by the microhistoche-mical elution method, the heterozygotes can be devided into three types: the reactive, the intermediate, and the non-reactive. Out of 44 cases of heterozygote, there are 29 cases of reactive type (65.9%), evidently being more than the other two types. Among 11 cases of heterozygotes with history of favism, there are 10 reactive including the intermediate. This illustrates that the occurrence of favism is more or less related to the degree of expressivity. Therefore, the reactive and intermediate types should be included as an object of prophylactic measures.

    蚕豆病是进食蚕豆后引起的一种急性溶血性疾病。己经查明,红细胞中缺乏6-磷酸葡萄糖脱氢酶是对蚕豆敏感的主要原因。这种酶缺乏是按伴性不完全显性规律遗传的。一般认为,携带此病理基因的杂合子不发病。本文探讨鉴定杂合子较敏感的方法,并研究杂合子是否发病。在比较了高铁血红蛋白还原试验微量洗脱法、微量比色法和谷胱甘肽稳定性试验后认为,前法较后二法敏感。 用上述三种方法检查了17例有蚕豆病史的女性,证明其中10例为杂合子,6例为纯合子。说明杂合子可以发病。若将杂合子按微量洗脱法显示的表现度分为三型:即反应型、中间型和非反应型,则有患病史的杂合子绝大多数属于反应型及中间型(11例中之10例)。说明杂合子是否发病与其表现度有关。故建议在预防工作中,将此二型列入预防对象。

    在抗锈育种过程中观察分析了不同材料对条锈病抗性的遗传行为,也为此单独设计了一些试验。结果表明:(1)不同抗锈材料对条锈病抗性的遗传行为有显性、隐性、简单、复杂之别。所谓抗锈性遗传传递能力的“强”、“弱”是抗锈性的显、隐性遗传和抗锈基因数目多少的共同结果。(2)供试材料大多呈不完全显性或隐性遗传,呈完全显、隐性遗传的极少。感病亲本和锈菌生理小种都对显、隐性的表现有影响。(3)抗锈基因分析工作虽没有完成,但也看到不同材料抗锈性遗传的简单或复杂程度是有差异的,尤皮号、奥克曼、维尔、水原11等对条锈病抗性的遗传比较简单。并提出利用回交后代检验亲本抗锈性遗传简单或复杂的方法。(4)对抗锈性遗传行为不同的亲本材料的利用价值,进行抗锈基因分析的方法,以及今后抗锈性遗传研究的前景也进行了讨论。
