X chromosome nondisjunction in mus301 hemizygous females
| Genotype of mothers | Total no. larvae (N) | No. of wild-type larvae | No. of y larvae (X0 progeny) | % X chromosome nondisjunction |
|---|---|---|---|---|
| w | 3305 | 3304 | 1 | 0.12 |
| mus301094/Df | 328 | 313 | 15 | 17 |
| mus301422/Df | 1600 | 1495 | 105 | 23 |
| mus301660/Df | 202 | 176 | 26 | 41 |
| mus301094/Df(3L)ZP3 | 303 | 291 | 12 | 15 |
| mus301422/Df(3L)ZP3 | 148 | 138 | 10 | 24 |
| mus301660/Df(3L)ZP3 | 188 | 163 | 25 | 42 |
Females of a given genotype were crossed to y males and the presence of y larvae was scored, indicating that X chromosome nondisjunction had occurred. To avoid unspecific effects due to genetic background, the experiment was repeated with a second deficiency for mus301, Df(3L)ZP3.
