Question: 1 / 2700

Which process cannot occur in haploid cells?

Meiosis

Meiosis is a specialized type of cell division that reduces the chromosome number by half, resulting in haploid cells from diploid cells. Since haploid cells already contain a single set of chromosomes, they cannot undergo meiosis, which requires two sets of chromosomes to complete the process of generating gametes with genetic diversity.

In contrast, haploid cells can undergo mitotic division, leading to the replication of their genetic material and division into more haploid cells. Fertilization also involves haploid cells coming together to form a diploid zygote, and genetic recombination can occur within haploid cells during processes such as crossing over, but it does not involve meiosis itself. Therefore, meiosis is the only process listed that cannot occur in haploid cells.
