Question

2015 - q44
44 human body cells each have 46 chromosomes in their nuclei. meiosis is necessary in order to ensure that each gamete produced in the human body has -
f 12 chromosomes
g 23 chromosomes
h 46 chromosomes
j 92 chromosomes

Explanation:

Meiosis is a type of cell division that reduces the chromosome number by half. Human body cells (somatic cells) are diploid with 46 chromosomes. Gametes (sperm and egg cells) are haploid. So, the number of chromosomes in gametes is half of that in somatic cells. \(46\div2 = 23\).

Answer:

G. 23 chromosomes
