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
Answer: (c). 12,24,24
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.
