Question

If we ignore the effect of crossing over, how many different haploid cells arise by meiosis in a diploid cell having 2n=12?

• A. 8
• B. 16
• C. 32
• D. 64

Answer 1

Answer: (D)

64

In a meiotic cell division, the different types of haploid cells produced will be 2${}^n$, where n is the haploid chromosome number. In case, the diploid chromosome number is 12, the haploid chromosome number n will be 6. Thus different types of cells produced will be equal to 2${}^6$ or 64 types.

So, the correct answer is '64'
