SIB MATING WITH TWO LINKED LOCI
mating with one locus has beeii studied extensively by several authors. "!&RIGHT (1921) in terms of the correlation between uniting gametes, HAL-DANE (1937) using a generation matrix for the six possible mating types, and MALECOT (1948) using probability arguments, all produced the same recurrence relation of a measure of the degree of homozygosity, the inbreeding coefficient.
