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 a

nd 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:

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.
