Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The HAPLOID number for the Cat is 38. The number of chromosomes found in a Cat’s skin cell is:

A	19
B	38
C	76

Explanation:

Detailed explanation-1: -2n=38. So n=19. Therefore, 19 chromosomes are inherited from each parent. Gametes (haploid) have 19 chromosomes.

Detailed explanation-2: -Answer and Explanation: The chromosome number during mitosis always remains the same. If the cat cell had 38 chromosomes, the resulting daughter cells will also have 38 chromosomes.

Detailed explanation-3: -Cows have 60. Cats have 38. Fruit flies have 8. Humans have 46.

Detailed explanation-4: -The number of chromosomes does not correlate with the apparent complexity of an animal or a plant: in humans, for example, the diploid number is 2n = 46 (that is, 23 pairs), compared with 2n = 78, or 39 pairs, in the dog and 2n = 36 (18) in the common earthworm. There is an equally great range of numbers among plants.
