AcademicBiologyNCERTClass 10

In a tobacco plant, there are 24 chromosomes in male gametes.

Thus, the haploid number of chromosomes is 24. 

N= 24.

(i) The female gamete or an egg contains the haploid number of chromosomes. Therefore, there are N chromosomes or 24 chromosomes in the female zygote.


(ii) Zygote contains a diploid number of chromosomes.

Therefore, 2N is 2 x 24, which is 48 chromosomes.
