How many chromosomes are present in a normal human sperm cell?

• A. 46 chromosomes
• B. 23 chromosomes
• C. 22 chromosomes
• D. 24 chromosomes

Answer: (B)

A normal human sperm cell contains 23 chromosomes. In humans, the total number of chromosomes is 46, arranged in 23 pairs, with one chromosome of each pair inherited from each parent. During the process of meiosis, which leads to the formation of gametes (sperm and eggs), chromosome number is halved. Therefore, sperm cells carry just one chromosome from each pair, resulting in a total of 23 chromosomes. This is essential for sexual reproduction, as the sperm will combine with an egg, which also contains 23 chromosomes, to create a fertilized zygote with the full complement of 46 chromosomes.
