75%
25%

Answer 1

F1: All ebony

F2: 75% ebony and 25% yellow.

Step-by-step explanation:

Assuming that the ebony fly is heterozygous, it would carry one gene for yellow. So when crossed with a yellow fly they will have 75% ebony and 25% yellow offspring.

The offspring will inherit the dominant trait for ebony. But a few of the offspring will inherit all recessive traits for yellow.

The f1 generation will be all ebony.

The f2 will be 75% ebony and 25% yellow.

Hope this is correct, have a great day.
