Globally, the most common form of consanguineous union is between first cousins, in which the spouses share 1 ⁄ 8 of their genes inherited from a common ancestor, and so their progeny are homozygous (or more correctly autozygous) at 1 ⁄ 16 of all loci (r = 0.0625). [27]

It follows that for first cousin progeny, F = 0.0625, that is, 1/16 loci predictably are homozygous, whereas for second cousins, F = 0.0156, that is, 1/64 of loci are homozygous. [ 25 ] A 1990 study conducted in South India found that the incidence of malformations was slightly higher in uncle-niece progeny (9.34%) compared to the first cousin ...
