Question

1. Produce gametes.
2. Reduce the number of chromosomes.
3. Introduce genetic variability.
4. Produce cells for tissue repair.
5. Divide somatic cells into new cells with identical characteristics.

Answer 1

1,2,3
Rationale 1: In the production of reproductive cells (gametes), there is a reduction of chromosome numbers by half (from diploid [46] to haploid [23]), so that when fertilization occurs, the normal diploid number is restored. This introduces genetic variability.

Rationale 4: The purpose of mitosis is to produce cells for growth and tissue repair. Cell division is characteristic of all somatic cells.
Rationale 5: The purpose of mitosis is cell division to create cells having the characteristics of all somatic cells.
