Which of the following is true about daughter cells produced by mitosis?
A
They are genetically diverse from the parent cell.
B
They contain half the number of chromosomes as the parent cell.
C
They are produced in the process of meiosis.
D
They are genetically identical to the parent cell.
Verified step by step guidance1
Understand that mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Recall that the primary purpose of mitosis is to ensure that each daughter cell receives an exact copy of the parent cell's DNA, making them genetically identical to the parent cell.
Recognize that genetic diversity is not a characteristic of mitosis; instead, it is a feature of meiosis, which involves recombination and independent assortment.
Note that mitosis does not reduce the chromosome number; it maintains the same chromosome number as the parent cell, unlike meiosis, which reduces the chromosome number by half.
Conclude that the correct statement about daughter cells produced by mitosis is that they are genetically identical to the parent cell.
