  1. The distribution of the four haplotypes among the subpopulations of sperm is not random. The haplotypes are Mc1r Cave/Oca2 Surface (MC OS), Mc1r Surface/Oca2 Cave (MS OC), Mc1r Cave/Oca2 Cave (MC OC), and Mc1r Surface/Oca2 Surface MS MO. Entries in italics are considered significant with z > 2
