Question

A haploid parent produces gametes by $\dots a\dots$ division while diploid parent produces gametes by $\dots b\dots$ division

• A. a-meiotic, b-amitotic
• B. a-meiotic, b-mitotic
• C. a-mitotic, b-meiotic
• D. a-amitotic, b-meiotic

Answer 1

The correct option is C a-mitotic, b-meiotic

Mitosis
Mitosis or equational cell division results in the formation of two daughter cells from a single parent cell. The daughter cells have the same number of chromosomes compared to the parent cell.

Meiosis
Meiosis or reductional cell division results in the formation of four daughter cells from a single parent cell. The daughter cells have half the number of chromosomes compared to the parent cell.

Gametes
Gametes are haploid cells that are produced by the reproductive organs of an organism. Male and female gametes fuse during fertilisation to produce a diploid zygote that grows into an entire organism. Gametes have to be haploid in nature to maintain the diploid number of chromosomes in the zygote after their fusion.

Gamete formation in haploid organisms
Cells in the reproductive organs of haploid organisms undergo mitotic divisions to produce gametes which are also haploid in nature.

Gamete formation in diploid organisms
In order to produce haploid gametes, cells in the reproductive organs of diploid organisms undergo meiotic division.

Final answer
a.a-mitotic, b-meiotic
