Final answer:
Gametic disequilibrium refers to the non-random association of alleles in gametes, contrasting with the expected random distribution due to independent assortment during meiosis.
Step-by-step explanation:
The general case of gametic disequilibrium refers to the non-random association of alleles in gametes. This is in contrast to the expected outcome from independent assortment and recombination that occurs during meiosis. Typically, independent assortment results in gametes with unique combinations of chromosomes and alleles, and the sorting of chromosomes from each homologous pair into pre-gametes appears to be random.
However, gametic disequilibrium describes a situation where certain combinations of alleles are inherited together more frequently than would be expected from a random formation of gametes. This can occur for various reasons, such as physical proximity of genes on a chromosome (linkage) or selection for certain allele combinations due to evolutionary pressures.
