Answer the following question given this paragraph: Sperm are male gametes , or reproductive cells. When a male gamete meets a female gamete, they can form a new organism. Sperm form when certain cells in the male reproductive system divide by meiosis , resulting in cells with half the amount of DNA as a regular "body" cell. More precisely, sperm cells are haploid sex cells, having one set of chromosomes. Regular body cells are diploid, having two set of chromosomes. As there are 46 chromosomes in a diploid human cell, how many are in a human sperm cell?. Q: How many chromosomes are in a diploid human cell? Choices: - 46.63 chromosomes - 41 - 47 - 46 chromosomes A:
46 chromosomes
