英文释义

名词 n.
  1. One of a number of alternative forms of the same gene occupying a given position, or locus, on a chromosome.
    — Genes are competing directly with their alleles for survival, since their alleles in the gene pool are rivals for their slot on the chromosomes of future generations. Any gene that behaves in such a way as to increase its own survival chances in the gene pool at the expense of its alleles will, by definition, tautologously, tend to survive.
