Practice Question

In the human. the haploid number of chromosomes is:

Answer Choices:

Correct Answer:

23 and the result of meiosis

Rationale:

👉 Humans have 46 chromosomes in diploid somatic cells, arranged in 23 pairs.

👉 During meiosis, gametes (sperm and eggs) are produced with only 23 chromosomes, which is the haploid number.

👉 This halving of the chromosome number is critical because at fertilization, the sperm and egg combine to restore the full diploid number of 46 chromosomes.

👉 The haploid number is 23, and it is specifically the result of meiosis
