Single Choice
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$$12, 24, 24$$
Correct Answer
D$$24, 12, 24$$
Solution
Chromosome number in male gamete of rice plant is $$n = 12$$ therefore chromosome number in female gamete would also be $$12$$. Zygote is diploid as it is the product of fertilization and the cells of the seeding would be meiocytes and other diploid cells. Hence, the chromosome number in both zygote and cells of seeding will be $$2n = 24$$.
So, the correct answer is '12,24,24'.
