Table 2. Association between sex and genotype at the putative ZW locus (chromosome 5 at 26.3 cM).
ZZ | ZW | WW | |
---|---|---|---|
Male | 57% | 46% | 0 |
(n=52) | (n=82) | ||
Female | 43% | 54% | 100% |
(n=40) | (n=95) | (n=69) |
All homozygous ‘W' individuals are female, while heterozygotes were slightly skewed towards females and homozygous ‘Z' individuals were slightly skewed towards males, due to additional loci and their interactions.
