When both parents are heterozygous for a deleterious recessive allele, according to Mendel's laws of inheritance, there is a 25% chance that any given offspring will inherit two copies of the recessive allele (one from each parent) and thus be homozygous recessive. This calculation is independent of the coefficient of relatedness between the parents.
