Multiple Choice
Which statement best describes the daughter cells produced by mitosis?
A
They are genetically unique due to crossing over and have half the chromosome number of the parent cell.
B
They differ genetically because homologous chromosomes assort independently during division.
C
They are genetically identical but have half the chromosome number of the parent cell.
D
They are genetically identical to the parent cell and to each other, maintaining the same chromosome number.
Verified step by step guidance1
Step 1: 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, primarily for growth and tissue repair.
Step 2: Recall the chromosome number during mitosis. The chromosome number is maintained because the DNA is replicated before mitosis, and then equally divided, so each daughter cell has the same number of chromosomes as the parent cell.
Step 3: Differentiate mitosis from meiosis. Unlike meiosis, mitosis does not involve crossing over or independent assortment of homologous chromosomes, so genetic variation is not introduced during mitosis.
Step 4: Analyze the statements given. Statements mentioning genetic uniqueness or half the chromosome number describe meiosis, not mitosis.
Step 5: Conclude that the correct description of daughter cells produced by mitosis is that they are genetically identical to the parent cell and to each other, maintaining the same chromosome number.
