The ratio for BB:Bb:bb is 1:2:1.....so number of homozygous (BB) individuals is equal to no. of recessive (bb) individuals . AS BOTH RATIOS ARE EQUAL, NO. OF BB INDIVIDUALS=no. of bb individuals=60
so your answer is 60

Dear student 
Since we believe that the homozygous recessive for this gene (q2) represents 4% (i.e. = 0.04), the square root (q) is 0.2 (20%). The frequency of the dominant allele. Answer: Since q = 0.2, and p + q = 1, then p = 0.8 (80%). The frequency of heterozygous individuals.
