Gametes or we say reproductive cell, their cells divide or duplicate through meiosis, not mitosis.<span />
<span>This question can be solved using Hardy-Weinberg equation. The equation would be:
a+b=1
</span>a^2+2ab+b^2=1
<span>There are 360 individual with genotype bb which means
b^2=360/1000
b=</span>√0.36= 0.6
The frequency of b allele would be: 0.6
