Question

Which of these statements is true

Answer 1

A.
Mitosis produces four identical cells.

B.
Mitosis brings genetic variety to a species.

C.
Meiosis involves two cycles of cell division.

D.
Meiosis helps your body heal itself.

Answer 2

The answer is not A, because mitosis produces 2 identical cells.

The answer is not B, because mitosis does not bring any type of variety or new characteristics to a species, everything is identical.

The answer is not D, because it is mitosis that helps the body heal itself. Meiosis is the type of cellular reproduction that occurs when the DNA of two different cells combine to create genetic variety (sexual reproduction, forming the offspring). Mitosis, however, makes the same type of cell again and again. So, if the muscle tissue somewhere in your body is damaged, mitosis will occur to build up that type of tissue again and heal your body.

The answer would be C, because meiosis does, in fact, undergo two cycles of the cell division process - Meiosis I and Meiosis II. Different things happen during the phases of cell division between meiosis I and meiosis II. For example, DNA replication occurs in meiosis I, but does not occur in meiosis II.
