Inbreeding increases homozygosity

WebInbreeding increases homozygosity, which in turn increases the frequency of harmful recessive alleles, resulting in inbreeding depression. Inbreeding depression on fertility reduces the profitability of dairy farming by decreasing the lifetime milk production of cows and by increasing insemination and veterinary costs. Continuous homozygous ... WebIt appears that inbreeding causes an increase in homozygosity at many genetic loci with small deleterious effects on homeostatic pathways, resulting in increased disease risk. The results indicate that between 23% and 48% of the incidence of these disorders in this population sample (other than type 2 diabetes) could be attributed to recent ...
