It can be classified in (a) a large group that is triggered by mutagens, (b) a large group triggered by promoters, (c) a small group that develops "spontaneously", and (d) a small group that is inherited according to Mendelian Laws.
The type of chromosome reproduction differs from the diploid type in as much as eutetraploid plants do not precisely reproduce the chromosome number and gene content, fundamentals on which are based the Mendelian laws of inheritance.
Two Rh serotypes from a Slovenian family that were unexpected according to the Mendelian laws were characterised genotypically.
The complete transgene was, however, inherited in all cases according to Mendelian laws as observed by Southern analysis.
Of these the Mendelian laws of heredity are an example.
