Background: While the adoption of genomic evaluations in livestock has increased genetic gain rates, its effects on genetic diversity and accumulation of inbreeding have raised concerns in cattle populations. Increased inbreeding may affect fitness and decrease the mean performance for economically important traits, such as fertility and growth in beef cattle, with the age of inbreeding having ...

Introduction. Inbreeding in US dairy cattle has increased steadily over the past several decades. The average inbreeding coefficient of Holsteins rose from 0.4% in 1970 to 5.8% in 2012 (USDA-AIPL, 2012), with the majority of this increase attributed to intense selection pressure on bulls.Some Holstein bulls used in AI have had as many as 250,000 milking daughters or 5,000 progeny-tested sons ...Breeding Program Basics. Evaluating colony performance and making informed selections of breeding stocks requires meticulous planning, rigorous record keeping, and regular inspections. Because honey bee queens naturally mate in flight with multiple males of unknown lineage, making controlled crosses requires specialized training and equipment.As scientists discovered in the 1960s, the mutation that causes the Smurf-like skin is carried by a recessive gene, and it takes two people with that same gene to produce a blue child. "If you took any random person in the population, maybe one in 100,000 would carry this gene, if that many," says Ricki Lewis, a science writer and author of the …

Around 10.4% of the world population presents a consanguineous relationship as second cousins. 1. hesi premature infant case study Inbreeding depression can also be generated by epistasis between dominance effects across loci, such that favorable gene combinations among heterozygous genotypes decrease in frequency during the inbreeding process (Jain and Allard, 1966).
