Next, Morgan crossed the red-eyed F1 males with the red-eyed F1 females to produce an F2 generation. The Punnett square below shows Morgan's cross of the F1 males with the F1 females.

Drag the labels to their appropriate locations to complete the Punnett square for Morgan's F1 x F1 cross.

Drag pink labels onto the pink targets to indicate the alleles carried by the gametes (sperm and egg).

Drag blue labels onto the blue targets to indicate the possible genotypes of the offspring.

Labels can be used once, more than once, or not at all.

Vaughan · Answer 1

When a homozygous red-eyed female was crossed with the white-eyed male (w+w + * wY), the resulting F1 females were w+w and the F1 males were w + Y. Crossing the F1 males and F1 females would yield these results:

All the F2 females would have red eyes, although some would be homozygous (w+w+) and others would be heterozygous (w+w).

Half the F2 males would have red eyes (w + Y), and half would have white eyes (wY).
