Kinship and inbreeding coefficients
The kinship coefficient is a measure of relatedness between two individuals.
It represents the probability that two genes, sampled at random from each individual are identical
(e.g. the kinship coefficient between a parent and an offspring is 0.25)
The inbreeding coefficient is the kinship coefficient between the individual’s parents, and
measures the probability that the two alleles of a gene are identical by descent in the same individual (autozygosity).
It is zero if the individual is not inbred.
