WebJul 8, 2015 · The correlation between FPED and genotype based inbreeding coefficients were 0.74 using true allele frequencies and 0.68 using estimates of base frequencies in dairy cattle [ 39 ]. In Jersey cattle, correlation of FPED and FROH was 0.65 using 10–100 SNP thresholds [ 37 ], which agrees with our findings. WebJan 17, 2024 · Variant data can also be used to estimate the coefficient of inbreeding (F), which is a metric that describes the distribution of variants in a population. According to the Hardy–Weinberg (HW) principle, F = 0 for a given variant indicates HW equilibrium. By this measure, a fully inbred strain has an inbreeding coefficient of F = 1.0 (100%).
WebThe inbreeding coefficient can have any value between 0 and 1.0, although it is unlikely for it to have a value much above . 5 in most herds of livestock. These coefficients are relative to a particular population. It is fairly easy to have it approach 1.0 in plant species where self-fertilization is possible.
