Deviated from hwe
WebIn general: how far from the normal. In statistics: the difference between a single value and the mean of all values in a set. WebThe deviation from HWE can be tested using any one of the following three methods: The Chi square statistic for asymptotic tests has been used to evaluate the overall discordance of genotype frequencies at each locus or population combination (Hammond et al., 1994; Deka et al., 1995). The test is performed for every breed at each locus.

WebA proportion of markers showing significant deviation from HWE at different values of inbreeding, sample size, and nominal significance threshold is shown in Table 9.1. While deviation of this proportion from nominal one is minimal at large αs, small sample sizes and coefficients of inbreeding, it may be 10-fold and even 100-fold higher than ... WebSep 1, 2008 · The inbreeding coefficient (F(is)) is a measure of the degree and direction of deviation from HWE. Among studies investigating SNPs, there was a significant correlation between F(is) and HWD (R = 0.191; p = 0.002), indicating that the greater the deviation from HWE, the greater the deficit of heterozygotes.
