The male gametes of rice plant have 12 chromosomes in their nucleus. The chromosome number in the female gamete, zygote and the cells of the seedling will be, respectively.

A

`12, 24, 12`

B

`24, 12, 12 `

C

`12, 24, 24`

D

`24, 12, 24`

Text Solution

Verified by Experts

The correct Answer is:
C
Gametophytic structure (n) of rice plant contain 12 chromosomes and sporophytic structure (2n) of rice contain 24 chromosomes.
Female gamete (n) = 12,
Zygote (2n) = 24,
The cells of the seedling (2n) = 24.
