The output is the inbreeding coefficient 'F' (fixation) statistic, which for large sample sizes converges to the probability that an individual's two alleles are identical by descent, provided that cosanguinity is the only source of deviation from Hardy-Weinberg equilibrium. If this assumption is not true F may be negative and the ...Genomic inbreeding coefficients are dependent on assumptions about allele frequencies in the base population . These frequencies are usually unknown, therefore their choice is a challenging problem. In the US, base allele frequencies of 0.5 are used for calculating genomic inbreeding values.inbreeding, the mating of individuals or organisms that are closely related through common ancestry, as opposed to outbreeding, which is the mating of unrelated organisms.

The short answer is that inbreeding is a measure of the probability of identity by descent of two alleles at a given locus in a given individual. This concise definition itself is the problem.

Locus is the most concrete one, as it is ...The objective of linebreeding is to increase the influence of a particular ancestor (s) in the offspring. It also increases the reliability of your results to some extent. Linebred offspring are more likely to come out sharing the traits of their parents and other ancestors.

The fixation index is the average coefficient of inbreeding in a population.
