Answer:
the frequency of allele B is 0.7 and allele b is 0.3 in population’s gene pool.
Step-by-step explanation:
Allele frequency is how often an allele occurs in a gene pool relative to the other alleles for that gene
Genotype No. of Individuals No. of Allele B No. of Allele b
BB 30 30*2 =60 30*0 =0
Bb 10 10*1 =10 10*1=10
bb 10 10 *0 =0 10*2=20
Total 50 70 30
Total no. of alleles = 70+30 =100
The frequency of allele B :[tex]\frac{\text{number of B alleles}}{\text{total number of alleles}}[/tex]
:[tex]\frac{70}{100}[/tex]
:[tex]0.7[/tex]
The frequency of allele b :[tex]\frac{\text{number of b alleles}}{\text{total number of alleles}}[/tex]
:[tex]\frac{30}{100}[/tex]
:[tex]0.3[/tex]
Hence the frequency of allele B is 0.7 and allele b is 0.3 in population’s gene pool.
