WebZygosity (the noun, zygote, is from the Greek zygotos "yoked," from zygon "yoke") (/ z aɪ ˈ ɡ ɒ s ɪ t i /) is the degree to which both copies of a chromosome or gene have the same genetic sequence. In other words, it is the degree of similarity of the alleles in an organism..

WebClose inbreeding leads to homozygosis and, as a rule, to a decline in fit-ness. The latter-inbreeding depression-results in part from the expres-sion of deleterious recessive mutations that ordinarily are concealed by more nearly normal, dominant alleles. Because of the large numbers of loci Consider a large non-inbred population with mean fitness W. Then, the size of the population reduces to a new smaller value N (in fact, the effective population size should be used here), leading to a progressive increase of inbreeding. Then inbreeding depression occurs at a rate δ, due to (partially) recessive deleterious alleles that were present at low frequencies at different loci.

The opposite effect, inbreeding depression, results from repeated self-pollination and leads to a reduction in vigor.
