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

The correct option is D 64

Formula $2^{n}n=$ haploid number of chromosomes. 12 chromosomes (i.e.,) n = 6. According to our formula 2 pairs of chromosomes can recombine in $(2{)}^2$ ways and therefore 6 pairs in $(2{)}^6$ ways = 64 .
