During which phase is the chromosome number reduced from diploid to haploid?
Correct answer
D
Rationale
The correct answer is meiosis I. Meiosis is a specialized cell division process that occurs in sexually reproducing organisms to produce gametes (sperm and egg). In meiosis I, the chromosome number is reduced from diploid (2n) to haploid (n) by separating homologous chromosomes. This reduction in chromosome number is crucial for maintaining the correct chromosome count in sexually reproducing organisms and ensuring genetic diversity in offspring.
