Solution

The correct option is C Allosomes

  • Chromosomes can be categorised into two types based on their primary function.

  1. Allosomes: Allosomes are sex chromosomes. These chromosomes contain genes that determine the sex of an organism.
  2. Autosomes: All the chromosomes other than the sex chromosomes.

  • For example, humans have 22 pairs of autosomes (total 44) and one pair of sex chromosomes (the X and Y).

Hence, the correct answer is option B.
