Question

Select the statement(s) that accurately describe how meiosis affects the way in which traits are passed on from parents to offspring.

Meiosis ensures that offspring will have unique traits.

Meiosis creates four haploid cells that have different combinations of genes for each trait for each cell.

Meiosis prepare the gametes for sexual reproduction.

Meiosis is a type of cell division that is used to repair or replenish dead cells (skin cells) to maintain cellular homeostasis.

Meiosis creates four cells that have the same combinations of genes for each trait

Answer 1

Correct statements: 1, 2, and 3.

- Meiosis ensures that offspring will have unique traits. — Mostly true: meiosis generates genetic variation (by crossing over and independent assortment) so offspring are usually genetically unique, though "ensures" is a bit strong because identical outcomes are theoretically possible.

- Meiosis creates four haploid cells that have different combinations of genes for each trait for each cell. — True: meiosis produces four genetically distinct haploid gametes.

- Meiosis prepares the gametes for sexual reproduction. — True: meiosis produces haploid gametes needed for fertilization.

Incorrect statements:
- Meiosis is a type of cell division used to repair or replenish dead cells (skin cells) — False; that is the role of mitosis.
- Meiosis creates four cells that have the same combinations of genes for each trait — False; meiosis produces genetically different cells, not identical ones.
