Panmixia  (PANMIXIA)


The set of two genes of an individual at the same locus is called a genotype 1; the genotype is said to be homozygous 2 if the alleles are identical at a given locus; it is said to be heterozygous 3 in the opposite case. The phenotype 4 consists in the observable characteristics as determined by the genotype and the environment. If an heterozygous individual (AA’) cannot be distinguished from an homozygous individual (AA), the allele A is said to be dominant 5 over allele A’, and A’ is said to be recessive 6. Genes are subject to sudden and apparently random changes, called mutations 7. Panmixia 8 or random mating 8 insures uniform distribution of genes within populations.

  • 7. Mutation, n. - mutant, adj. or n.
