See the attached file for the same text, but formatted so that it's easier to read.

If an organism has the genotype AABB, the only possible gametes have the genotype AB.

In Prophase I (first step in meiosis), homologous chromosomes pair up. Each of the chromosomes is made up of 2 sister chromatids because the chromosomes have already replicated (this happened during interphase), so the cell looks like this:

A A A A

B B B B

If you can't see the diagram, there are 2 homologous chromosomes each made up of 2 sister chromatids, each will the alleles A and B. I'm assuming that the A and B genes are on the same chromosome. If they ...
