Which of the following normally results from meiosis in a human cell that contains 46 chromosomes?
  1. an egg cell with 46 chromosomes
  2. a liver cell with 23 chromosomes
  3. a blood cell with 46 chromosomes
  4. a sperm cell with 23 chromosomes
Explanation

Answer: D - A sperm cell with 23 chromosomes.

The correct answer is: a sperm cell with 23 chromosomes.

Meiosis is the process of cell division that produces haploid cells (cells with half the number of chromosomes as the parent cell) for sexual reproduction. In humans, the parent cell has 46 chromosomes, which are arranged in 23 pairs.

During meiosis, the chromosome number is reduced from 46 to 23 through two rounds of cell division, resulting in the formation of four haploid cells. In males, these haploid cells are sperm cells, each with 23 chromosomes. In females, one of the four haploid cells becomes an egg cell, also with 23 chromosomes.
