Inbreeding coefficient fis
Did you know?
The measures FIS, FST, and FIT are related to the amounts of heterozygosity at various levels of population structure. Together, they are called F-statistics, and are derived from F, the inbreeding coefficient. In a simple two-allele system with inbreeding, the genotypic frequencies are: $${\displaystyle … See more In population genetics, F-statistics (also known as fixation indices) describe the statistically expected level of heterozygosity in a population; more specifically the expected degree of (usually) a reduction … See more • Shane's Simple Guide to F-Statistics • Analyzing the genetic structure of populations See more A reformulation of the definition of $${\displaystyle F}$$ would be the ratio of the average number of differences between pairs of chromosomes sampled within diploid … See more • Malecot's method of coancestry • Heterozygosity • QST-FST analyses See more WebJan 16, 2024 · Inbreeding --het ['small-sample'] ['gz'] --ibc --het computes observed and expected autosomal homozygous genotype counts for each sample, and reports method-of-moments F coefficient estimates (i.e. ( - ) / ( - )) to plink .het.
