How do the daughter cells at the end of mitosis and cytokinesis compare with their parent cell when it was in G 1 of the cell cy
cle? a. The daughter cells have half the number of chromosomes and half the amount of DNA. b. The daughter cells have the same number of chromosomes and the same amount of DNA. c. The daughter cells have the same number of chromosomes and half the amount of DNA. d. The daughter cells have the same number of chromosomes and twice the amount of DNA. e. The daughter cells have half the amount of cytoplasm and half the amount of DNA.
b. The daughter cells have the same number of chromosomes and the same amount of DNA.
Explanation:
Mitosis is the cell division that maintains the DNA amount and chromosome number in daughter cells. This is due to the fact that each mitosis is preceded by one round of DNA replication in S phase.
For example, if the parent cell had 2n DNA in 46 chromosomes, the daughter cells at the end of mitosis and cytokinesis would also have 2n DNA in 46 chromosomes.
The majority of mutations are neutral in their effects on the organisms in which they occur. Beneficial mutations may become more common through natural selection. Harmful mutations may cause genetic disorders or cancer.
