Multiple Choice
In mitosis of a typical diploid somatic cell, what is the ploidy of the daughter cells produced relative to the parent cell?
A
Diploid; the daughter cells have the same ploidy as the parent cell
B
Tetraploid; the daughter cells have double the chromosome number of the parent cell
C
Haploid; the daughter cells have half the chromosome number of the parent cell
D
Aneuploid; the daughter cells typically gain or lose individual chromosomes during mitosis
Verified step by step guidance1
Step 1: Understand the definition of ploidy, which refers to the number of sets of chromosomes in a cell. A diploid cell (2n) has two complete sets of chromosomes, one from each parent.
Step 2: Recall that mitosis is the process of cell division that results in two daughter cells. The key feature of mitosis is that it maintains the chromosome number of the original cell.
Step 3: During mitosis, the chromosomes are duplicated during the S phase of interphase, so each chromosome consists of two sister chromatids. These chromatids are then separated into two new nuclei.
Step 4: Since the sister chromatids separate, each daughter cell receives one complete set of chromosomes, preserving the original diploid number (2n).
Step 5: Therefore, the ploidy of the daughter cells after mitosis is the same as the parent cell, which is diploid.
