The genetic basis of depigmentation of feathers chickens
Genes of the depigmentation of the feathers of chickens "MoD" and "mo" (mottled are) allele in allelomorphic series MoD, Mo+ and mo. Incomplete dominant depigmentation gene " MoD " with penetrance in heterozygote Mod/Mo+ 40%, and in heterozygote MoD/mo 90% is in some breeds and lines in the latent state. White chickens homozygous MoD/MoD may suffer from a visual defect-blindness with exophthalmos. Their egg production is less than black-white australorps’ (143 ± 3.0 eggs) and heterozygotes MoD/mo (155 ±2.3 eggs). Gene "mo" should include in parents’ form of crosses, so it alloust to except negative gene "MoD" in the homozygote and increases productive hybrids.
