Reduction of chromosome number occurs during
A) recombination.
B) meiosis.
C) somatic cell formation.
D) gene linking.

Question

Quizplus · Accepted Answer

Reduction of chromosome number occurs during meiosis, specifically during meiosis I, where homologous chromosomes separate and the resulting cells have half the chromosome number of the original cell. Recombination and gene linking may occur during meiosis but do not directly result in a reduction in chromosome number. Somatic cell formation does not involve meiosis and therefore does not result in a reduction of chromosome number.
