In a certain population, the frequency of three genotypes is as follows
Genotypes :
$BB$
$Bb$
$bb$
frequency :
$22\%$
$62\%$
$16\%$
What is the likely frequency of $B$ and $b$ alleles ?
In a certain population, the frequency of three genotypes is as follows
| Genotypes : | $BB$ | $Bb$ | $bb$ |
| frequency : | $22\%$ | $62\%$ | $16\%$ |
What is the likely frequency of $B$ and $b$ alleles ?
Frequency of $\mathrm{B}$ allele $=$ all of $\mathrm{BB}(100 \%)+1 / 2$ of $\mathrm{Bb}(50 \%)=22+31=53 \%$
$\Rightarrow$ Frequency of $b$ allele $=$ all of $b b(100 \%)+1 / 2$ of $B b(50 \%)=16+31=47 \%$
