In a curly pumpkin, the white color of the fruit A dominates over the yellow a, and the disc-shaped B-over

In a curly pumpkin, the white color of the fruit A dominates over the yellow a, and the disc-shaped B-over the spherical b. What will F1 and F2 look like from crossing a homozygous white globular pumpkin with a homozygous yellow disc?

According to the notation introduced in the problem statement, we write down a homozygous figured pumpkin with white spherical fruits as AA bb. This pumpkin produces Ab sex cells.

A homozygous pumpkin with yellow disc-shaped fruits will be aaBB, the germ cells it produces will be aB.

The F1 offspring will be AaBb, which will be expressed in the formation of white and disc-shaped fruits by all plants. These hybrids will produce sex cells ab, AB, aB and Ab.

The offspring of F2 pumpkin hybrids will include the following variants:

pumpkin with white disc-shaped fruits (AABB, AaBB, 2AABb, 4AaBb);

pumpkin with white globular fruits (2Aab, AAbb);

pumpkin with yellow disc-shaped fruits (aaBB, 2aaBb);

pumpkin with yellow spherical fruits (aabb).
