The haploid number of chromosomes in the human eggs and sperms are?
Correct answer: B. 23
- A. 22
- B. 23
- C. 21
- D. 24
Explanation
The egg and sperm cells, the reproductive cells or gametes, are haploid, meaning they contain only one set of chromosomes. In humans, the haploid number of chromosomes is 23.During meiosis, the process of cell division that produces gametes, the parent cell undergoes two rounds of cell division to produce four daughter cells, each with half the number of chromosomes as the parent cell. This ensures that when the egg and sperm fuse during fertilization, the resulting zygote will have the usual diploid number of chromosomes, which is 46 in humans.
