Question
State the difference between meiocyte and gamete with respect to chromosome number.
Advertisements
Solution
A meiocyte is a diploid (2n) cell containing two sets of chromosomes, while a gamete is a haploid (n) cell containing only one set of chromosomes. Thus, meiocytes have double the chromosome number compared to gametes.
