In a typical human somatic cell (2n = 46), how many chromosomes does each daughter cell have immediately after mitosis and cytokinesis?
A
92 chromosomes
B
23 chromosomes
C
46 chromosomes
D
It varies randomly between 23 and 46 chromosomes
Verified step by step guidance1
Recall that a typical human somatic cell is diploid, meaning it has two sets of chromosomes, one from each parent, totaling 46 chromosomes (2n = 46).
Understand that mitosis is the process by which a somatic cell divides to produce two genetically identical daughter cells, maintaining the chromosome number.
During mitosis, the chromosomes are duplicated during the S phase of interphase, so each chromosome consists of two sister chromatids, but the chromosome number count remains based on centromeres, not chromatids.
After mitosis and cytokinesis, the cell divides into two daughter cells, each receiving one copy of each chromosome, thus preserving the diploid number of 46 chromosomes.
Therefore, each daughter cell immediately after mitosis and cytokinesis will have 46 chromosomes, the same as the original parent cell.
