The probability that an individual taken at random from the population will be autozygous.

a measure of the genetic effects of inbreeding in terms of the proportionate reduction in heterozygosity in an inbred organism compared withthe heterozygosity expected with random mating.

The rate at which heterozygosity is reduced (or homozygosity is increased) per generation in the population.

The probability of homozygosity by descent (having common ancestors). The probability that a zygote obtains copies of the same ancestral gene from both its parents because they are related. The probability of autozygosity.

the probability that the two alleles present at a locus are identical by descent, i.e. are derived from the same ancestor.

the probability that two allelic genes united in a zygote are both descended from a gene found in an ancestor common to both parents; also the proportion of loci at which an individual is homozygous
