WebApr 17, 2015 · Wright’s FIS ( Wright 1951 ), or inbreeding coefficient, was introduced to measure excess of homozygotes, or heterozygote deficiency. Based on Wright’s definition, F I S = H exp − H obs H exp, where Hexp and Hobs are the expected and observed heterozygosities ( Nei 1977 ).

Assume . further that a sire from this herd had a 3.50 pounds per day feedlot ADG, while a younger half brother has not, as yet, been evaluated for feedlot ADG. Assuming no inbreeding, the coefficient of relationship between half brothers is 0.25.

WebAug 16, 2016 · An inbreeding coefficient is calculated as the probability percentage (%) for any allele (i.e. pair of genes at a specific location on the chromosome) to be identical by descent. Typical inbreeding coefficient percentages are set out in the table below. This is assuming no previous inbreeding between any parents.
