A human somatic cell contains how many chromosomes?
Correct answer: C. 46
- A. 23
- B. 44
- C. 46
- D. 92
Explanation
Human body cells are diploid with 46 chromosomes, which is 23 homologous pairs made up of 22 pairs of autosomes and one pair of sex chromosomes. Gametes are haploid and carry 23. The count of 92 would only appear briefly after replication if chromatids were miscounted as separate chromosomes, which they are not.
