Genes are located on chromosomes. 2. A human sperm cell contains 46 chromosomes.

Single correct option

Consider the following statements:
1. Genes are located on chromosomes.
2. A human sperm cell contains 46 chromosomes.
Which of the statements given above is/are correct?
  1. A. 1 only
  2. B. 2 only
  3. C. Both 1 and 2
  4. D. Neither 1 nor 2
Show answer and solution

Answer: (A) 1 only

Genes are segments of DNA arranged along chromosomes, so statement 1 is correct. Gametes are produced by meiosis, which halves the chromosome number; a sperm contains 23 chromosomes, the normal body cell having 46. Statement 2 is therefore false, and only statement 1 is correct.
