Question

Quizplus · Accepted Answer

Meiosis reduces the number of chromosomes in the cell by half, resulting in haploid cells. In contrast, fertilization doubles the number of chromosomes by combining two haploid cells to form a diploid zygote. Mitosis and binary fission do not involve a reduction in the number of chromosomes per cell. Syngamy is another term for fertilization and is not a process that reduces the number of chromosomes.
