Question

meiosis makes sperm and egg cells. in humans, sperm and egg cells each have____chromosomes. therefore a fertilized human egg cell (sperm and egg cell combined) would create a cell with____chromosomes.

Explanation:

Meiosis is a type of cell division that reduces the chromosome number by half. Human body cells (somatic cells) have 46 chromosomes. Sperm and egg cells (gametes) are produced by meiosis, so they have half the number of chromosomes as somatic cells. That is 23 chromosomes each. When a sperm (23 chromosomes) fertilizes an egg (23 chromosomes), the resulting fertilized egg (zygote) has 23 + 23 = 46 chromosomes.

Answer:

B. 23, 46
