If this trisomic male (ey+ ey-, gw+ gw-) is crossed with a (ey− ey−, gw− gw−) female, what proportion of the progeny will be phenotypically wild-type?

The Ey and the gw abbreviations stand for eyeless and gawky genes in the fruit fly Drosophila. A wild-type individual has at least one dominant allele for both of these genes.
In the cross presented below, you can see that 25% (shown in red) of the progeny would be wild-type and the rest of the progeny would show at least one recessive trait (eyeless or gawky)

This type of galaxy is an approximately ellipsoidal shape and a smooth, nearly featureless image. they are the largest single star systems, in the universe and are built by the collisions of many smaller galaxies.
