Question
An animal cell contains 36 chromosomes. How many chromosomes are there in its gametes and somatic cells? Gametes Somatic cells A 18 18 B 18 36 C 36 18 D 36 36
Solution
The correct answer is B.
In animals, somatic cells (body cells) are diploid (2n), which means they contain two sets of chromosomes. In this case, the animal cell has 36 chromosomes, so it's a diploid cell.
Gametes (sex cells), on the other hand, are haploid (n) and contain only one set of chromosomes. This is because during sexual reproduction, one gamete combines with another gamete, and the resulting offspring has a complete set of chromosomes.
So, in this case, the gametes of the animal would have half the number of chromosomes as the somatic cell, which is 18.
Therefore, the animal's gametes have 18 chromosomes and its somatic cells have 36 chromosomes.
