高中生物85年甲科本教科书(139页)对等位基因下了确切的定义。其它遗传学书中和有关辞书的等位基因的概念也与此基本上相一致。例如《简明生物学辞典》(湖北人民出版社1985月1第1版)中指出:“在同源染色体上,占据相同座位上一对不同状态的基因互称为等位基因。等位基因是由基因突变而成,改变了一个基因的原来状态,仍影响着同一性状”。另外,我们只要比较一下85年甲种版本与82年2月第1版(全一册)中“等位基因”的概念,就不难看出,85年甲种版本是对82年(全一册)版本的修正。我认为,“等位基因”的概念没有不妥之处。
The high school biology 85th Grade A textbook (139 pages) has an exact definition of alleles. The concept of alleles in other genetic books and related dictionaries is also basically consistent with this. For example, the “Concise Dictionary of Biology” (Hubei People’s Publishing House, 1st edition, 1985, 1st) states: “On homologous chromosomes, genes that occupy a pair of different states on the same locus are called alleles. The allele is Mutations in the gene change the original state of a gene and still affect the same trait.” In addition, as long as we compare the concept of “alleles” in the 85-year version and the first edition (all-in-one) in February, 82, it is not difficult to see that the 85-year version is for 82 years (all ones). Revision). I think the concept of “alleles” is not wrong.
