Question

Consider a diploid cell that contains three pairs of chromosomes designated AA , BB, and CC. Each pair contains a maternal and a paternal member (e.g., Amand Ap, etc.)

In mitosis, what chromatid combination(s) will be present during metaphase?

1. AmAm
2. CpCp
3. BpBp
4. AmAp
5. BmBp
6. CmCp

Answer 1

Answer:

The chromatid combinations present will be AmAm, CpCp and BpBp

Explanation:

In mitosis, there is no exchange of materials between homologous chromosomes, thus the paternal and the maternal member of chromosomes DO NOT exchange materials at all.

This simply yields chromatids combinations that are singly maternal as AmAm OR singly paternal as CpCp and BpBp
