6) An organism has three pairs of homologous chromosomes. If the centromeres were labeled A/a, B/b, and C/c (where the slash line distinguishes one chromosome from its homologue), what chromosome (centromere) combinations would you expect to occur in the gametes of this organism?

Respuesta :

Answer:

Gametes are as; ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc.

Explanation:

1. As given, three pair of homologous chromosomes, labeled as A/a, B/b and C/c.

2. so we can also write it as AaBbCc

3. As meiosis occurs, every gamete inherit one chromosome from each pair of homologous chromosome, and each pair inherit independently. In meiosis, one  diploid cell produce four haploid daughter cells,

4. So, we can get different combination; as

ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc.
