Which of the following is a key difference between mitosis and meiosis?
Genetic variation occurs in meiosis; mitosis results in two identical daughter and parent cells.
There is no interphase before meiosis occurs.
Mitosis involves two cells divisions, while meiosis involves only one.
All of these choices are key differences.
Mitosis is significant in helping to maintain the continuation of a species by
producing gametes that are genetically different
creating somatic cells with half the number of chromosomes as the parent cell
producing an unequal amount of egg and sperm
allowing an organism to reproduce asexually to create identical copies of themselves
