Inbreeding coefficient fis

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 … See more • Malecot's method of coancestry • Heterozygosity • QST-FST analyses See more WebNov 29, 2024 · An Fis of zero indicates a level of inbreeding equal to the expected value …

WebFeb 25, 2024 · For all loci, the obtained values of the inbreeding coefficient were negative, except for the ETH10 locus. Negative inbreeding coefficient values ranged from Fis = −0.234 at the BM1824 locus to Fis = −0.034 at the TGLA126 locus, where the recorded excess of heterozygotes ranged from 3% at TGLA126 to 19% at BM1824. Web(HWE) (Table 2). If all the loci are in'HWE, Fis will be zero and FIT will be equal FST.
