The diagram shows a cell with two similar pairs of chromosomes. Due to independent assortment, what are all the possible combinations of alleles that could be found in the gametes? a AB, Ab, aB, and ab b AaBb and ABab c Aa, Bb, AA, and bb d AB and Ab

Answer 1

To determine all the possible combinations of alleles that could be found in the gametes due to independent assortment, we need to consider the combinations of alleles from each pair of chromosomes.

Assuming we have two genes (let's say for simplicity they are A/a and B/b):

1. The combinations of alleles from one gene (A/a) can be either A or a.
2. The combinations of alleles from the other gene (B/b) can be either B or b.

Using independent assortment, we can combine these alleles in the following ways:

1. A from A/a and B from B/b → AB
2. A from A/a and b from B/b → Ab
3. a from A/a and B from B/b → aB
4. a from A/a and b from B/b → ab

Thus, the possible combinations of alleles in the gametes are: AB, Ab, aB, and ab.

From your options, the correct answer is: a AB, Ab, aB, and ab.
