Question

consider a diploid cell that contains three pairs of chromosomes designated AA, BB, and CC. each pair includes a maternal and paternal member. during meiosis I, assuming no crossing over, what chromatid combinations will be present at the completion of prophase I

Answer 1

Answer:

There will still be six chromosomes but 12 sister chromatids

Explanation:

In meiosis 1, at the interphase (the S (synthesis) phase), replication of DNA occurs leading to the duplication of each chromosomes which at that point is just a sister chromatid with the centromere at the middle for each chromosome.

After interphase, at prophase 1, the chromosomes found will be two sister chromatids with the centromere at the middle for each chromosome.
