Explanation:

In human reproduction, gametes (egg and sperm) are haploid, meaning they have half the number of chromosomes of a normal somatic cell. A normal human somatic cell has 46 chromosomes, so gametes (egg and sperm) each have 23 chromosomes. When fertilization occurs, the egg (with 23 chromosomes) and sperm (with 23 chromosomes) unite to form a zygote. The zygote then has 23 + 23 = 46 chromosomes. So the egg and sperm each have 23 chromosomes, and the zygote has 46 chromosomes.

Answer:

B. 23, 46
