The given genotype is Aabb×aaBb.

To determine the possible genotypes of the offspring, we need to consider the possible combinations of alleles from each parent.

The genotype Aabb can be broken down into two alleles: A and b. Similarly, the genotype aaBb can be broken down into two alleles: a and B.

When these two genotypes are crossed, we can consider the possible combinations of alleles for each trait separately.

For the first trait (A or a), the possible combinations are:

- A from the first parent and a from the second parent: Aa
- a from the first parent and a from the second parent: aa

For the second trait (B or b), the possible combinations are:

- B from the first parent and b from the second parent: Bb
- b from the first parent and b from the second parent: bb

Combining the possible combinations for each trait, we get the following genotypes for the offspring:

- AaBb
- Aabb
- aaBb
- aabb

Therefore, the possible genotypes of the offspring are AaBb, Aabb, aaBb, and aabb.
