During mitosis in a human somatic cell, how many chromosomes will each daughter cell have after cytokinesis?
A
An unpredictable number because chromosomes are randomly segregated in mitosis
B
23 chromosomes
C
92 chromosomes
D
46 chromosomes
Verified step by step guidance1
Recall that human somatic cells are diploid, meaning they contain 46 chromosomes (23 pairs) before mitosis begins.
Understand that during mitosis, the chromosomes are duplicated during the S phase, so the cell temporarily has 92 chromatids (46 chromosomes each consisting of two sister chromatids).
During mitosis, specifically in anaphase, the sister chromatids are separated and pulled to opposite poles of the cell.
After cytokinesis, the cell divides into two daughter cells, each receiving one copy of each chromosome (one chromatid from each pair).
Therefore, each daughter cell ends up with the original diploid number of chromosomes, which is 46 chromosomes.
