CP Biology – Inheritance Practice Test

Number of chromosomes inherited from each parent?

46 from each parent. 22 from each parent. 24 from the mother and 22 from the father. 23 from the mother and 23 from the father.

Correct Answer:

23 from the mother and 23 from the father.

Explanation:

Humans have 23 pairs of chromosomes in most cells, totaling 46. Each parent contributes one chromosome to every pair through their gametes. Gametes are haploid, containing 23 chromosomes. When a sperm and egg fuse, the resulting zygote has 46 chromosomes: 23 from the mother and 23 from the father. So the number inherited from each parent is 23.
