Multiple Choice
In a typical diploid somatic cell, what is the primary result of mitosis?
A
Two genetically different diploid daughter cells produced by homologous chromosome pairing and crossing over
B
Four genetically distinct haploid daughter cells with half the chromosome number of the parent cell
C
One diploid cell and one haploid cell produced by reduction division
D
Two genetically identical diploid daughter cells with the same chromosome number as the parent cell
Verified step by step guidance1
Understand the purpose of mitosis: Mitosis is a type of cell division that results in two daughter cells, each genetically identical to the parent cell, maintaining the same chromosome number.
Recall the chromosome number in a typical diploid somatic cell: Diploid cells have two sets of chromosomes (2n), one from each parent.
Recognize that mitosis does not involve homologous chromosome pairing or crossing over; these processes occur during meiosis, not mitosis.
Note that mitosis produces two daughter cells, not four, and both daughter cells retain the diploid chromosome number, unlike meiosis which produces haploid cells.
Conclude that the primary result of mitosis is two genetically identical diploid daughter cells with the same chromosome number as the parent cell.
