  1. aOut of 55 BC offspring, 40 were females of which half were translucent (od) individuals (expected). Segregation of 16 Z-linked markers with od phenotype was tested in these individuals.
  2. bSegregation of od and normal phenotypes as observed in 262 BC offspring.
  3. Note that χ2-values for none of the Z-linked markers except for OPA-071352, OPR111200, OPT-14583, and TA(CAG)4 deviated significantly (P>0.01).
