Fofino [41]

Answer: .374 and .626

Explanation:

5. total number of alleles = 4712 + 2816 = 7528

       frequencey of B allele = B allele / total number of alleles --> 2816/7528 = 0.374                

             

6. total number of alleles =  4712 + 2816 = 7528

   freq of b allele = b allele/total number of alleles --> 4712/7528 = 0.626

We can confirm our answer as correct because if we add up the answers to 5 and 6 we should get one:

0.374 + 0.626 = 1
