互为等位基因的两个基因一定具有相同的碱基数量,为什么是错的?
如题
互为等位基因的两个基因一定具有相同的碱基数量,为什么是错的?如题
当然是不一样的了,等位基因只是一种控制相同性状的不同基因
等位基因是控制一对相对性状的两种不同形式的基因。就是说是不同的基因那么就有可能碱基数量是不同的

An allele is one of a series of different forms of a gene. The word is a short form of allelomorph ('other form'), which was used in the early days of genetics to describe variant forms of a gene detected as different phenotypes. Alleles are now understood to be alternative DNA sequences at the same physical gene locus, which may or may not result in different phenotypic traits. In any particular diploid organism, with two copies of each chromosome, the genotype for each gene comprises the pair of alleles present at that locus, which are the same in homozygotes and different in heterozygotes.
Therefore, 2 alleles may or may not have same base number.
