WebNov 30, 2024 · The genetic and molecular basis of heterosis has long been studied but without a consensus about mechanism. The opposite effect, inbreeding depression, results from repeated self-pollination and leads to a reduction in vigor. A popular explanation for this reaction is the homozygosis of recessive, slightly deleterious alleles upon inbreeding. WebInbreeding and homozygosis in bees. CROW JF, ROBERTS WC.

WebA transgenic individual can later be bred to homozygosity and maintained as an inbred line to reduce the need to confirm the genotype of each individual. In cultured mammalian cells, such as the Chinese hamster ovary cell line, a number of genetic loci are present in a functional hemizygous state, due to mutations or deletions in the other alleles.

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.
