Crossing over on the X chromosome in mei-38 females
| Genetic interval (distance in cM)

| Female genotype | w–cv or pn–cva | cv–m | m–f | f–y+b | Total map (cM) | Total progeny |
| y w mei-38/y mei-38 cv m f·y+ | 10.9 | 22.2 | 16.5 | 7.5 | 57.1 | 921 |
| y mei-38/y pn cv m f·y+ | 12.7 | 24.7 | 14.6 | 4.5 | 56.5 | 1237 |
a
In the mei-38 homozygote, the w–cv interval was measured, while in the mei-38/+ experiment, the pn–cv interval was measured, which is only ∼1 cM larger (Lindsley and Zimm 1992).
b
The y+ marker is tightly linked to the centromere and the f–y+ interval includes the X chromosome centromere.
