Mitosis vs. Meiosis

What is the primary purpose of mitosis?

Used for growth, repair, and replacement of cells.

In which type of cells does mitosis occur?

In body (somatic) cells.

What type of cells does meiosis produce?

Gametes (sperm and egg cells).

How many divisions occur in mitosis?

1 division.

How many daughter cells are produced by meiosis?

4 daughter cells.

What is the chromosome number in daughter cells produced by mitosis?

Same as the parent cell.

What is the chromosome number in daughter cells produced by meiosis?

Half of the parent cell.

What type of cells are produced by meiosis?

Gametes (sex cells).

What genetic similarity do daughter cells from mitosis have?

Identical to the parent cell.

What genetic variation occurs in meiosis?

Crossing over, meiosis creates genetic variation

What is crossing over in meiosis?

Chromosomes exchange pieces of DNA during Prophase I.

What is independent assortment in meiosis?

Chromosomes line up randomly during Metaphase I.

What happens during prophase of mitosis?

Chromosomes condense and the nuclear membrane disappears.

What is the end result of meiosis II?

Four haploid cells form.

What mnemonic can help remember the stages of mitosis?

PMAT: Prophase, Metaphase, Anaphase, Telophase.

What is the chromosome number in human body cells?

46 chromosomes (2n).

What is the chromosome number in human gametes?

23 chromosomes (n).

What is the key difference in the purpose of mitosis and meiosis?

Mitosis is for growth and repair; meiosis is to make gametes.

What happens during anaphase of mitosis?

Sister chromatids separate.

What is a memory trick for mitosis?

Mitosis = Maintain chromosome number.

What is a memory trick for meiosis?

Meiosis = Make gametes and genetic variation.
