In Drosophila, a cross between males expressing the three X-linked recessive traits, scute bristles (sc), sable body (s) and vermilion eyes (v) and wild type females. What progeny are expected? If you take a male and a female from this group and cross them you get the following results:
| genotypes | sex | number | ||
| + | + | + | females | 1000 |
| sc | s | v | males | 314 |
| + | + | + | males | 280 |
| + | s | v | males | 150 |
| sc | + | + | males | 156 |
| sc | + | v | males | 46 |
| + | s | + | males | 30 |
| sc | s | + | males | 10 |
| + | + | v | males | 14 |
