WebThe relation between the frequencies of expected versus observed heterozygotes allows us to determine the inbreeding coefficient, F = (He - Ho)/He (subscripts e and o mean expected and observed, respectively). One effect of inbreeding is to increase the frequency of homozygotes (and thus, necessarily, decrease the frequency of heterozygotes). christmas smash cake woolworths https://agriculturasafety.com

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. It is fairly easy to have it approach 1.0 in plant species where selffertilization is possible. There are also some lines of laboratory animals with very high average inbreeding coefficients.
