Scelta multipla
In meiosis, how many diploid parent cells undergo division to produce gametes in a single meiotic event?
A
Two diploid parent cells divide to ultimately produce four haploid cells total.
B
One diploid parent cell divides to ultimately produce two haploid cells.
C
Four diploid parent cells divide to ultimately produce four haploid cells.
D
One diploid parent cell divides to ultimately produce four haploid cells.
Guida verificata passo dopo passo1
Understand that meiosis is a type of cell division that reduces the chromosome number by half, producing haploid gametes from diploid parent cells.
Recall that one diploid parent cell undergoes meiosis, which consists of two rounds of division: meiosis I and meiosis II.
Recognize that meiosis I separates homologous chromosomes, and meiosis II separates sister chromatids, resulting in four haploid daughter cells from one diploid parent cell.
Note that each of the four haploid cells contains half the chromosome number of the original diploid cell, making them suitable as gametes.
Therefore, the number of diploid parent cells that divide to produce gametes in a single meiotic event is one, which produces four haploid cells.
