Question

A geneticist analyzes the four products of a meiosis for an Aa Bb plant and finds that two of the products have the AB alleles and the other two products have the ab alleles. Is this consistent with the principle of independent assortment? Assume that crossing over does not occur.

Answer 1

Answer:

No, this is not consistent with the principle of independent assortment.

Explanation:

The principle of independent assortment states that alleles from different genes assort independently. This means that if a plant has a genotype Aa Bb, all four alleles (A, a, B, and b) are going to segregate equally, so we will have the following four gametes after meiosis:

- AB

- Ab

- aB

- ab

If the researcher finds that two of the four products are AB, probably there would be a deviation of Mendel's laws.
