Vedclass · Answer

(A) According to the Hardy-Weinberg principle,the frequency of an allele in a population can be calculated from the genotype frequencies.$1$. Frequency of $B$ allele $(p)$: This is calculated as the frequency of the homozygous dominant genotype $(BB)$ plus half the frequency of the heterozygous genotype $(Bb)$.Frequency of $B = 	ext{Frequency of } BB + \frac{1}{2} 	imes 	ext{Frequency of } Bb$Frequency of $B = 22\% + \frac{1}{2} 	imes 62\% = 22\% + 31\% = 53\% = 0.53$.$2$. Frequency of $b$ allele $(q)$: This is calculated as the frequency of the homozygous recessive genotype $(bb)$ plus half the frequency of the heterozygous genotype $(Bb)$.Frequency of $b = 	ext{Frequency of } bb + \frac{1}{2} 	imes 	ext{Frequency of } Bb$Frequency of $b = 16\% + \frac{1}{2} 	imes 62\% = 16\% + 31\% = 47\% = 0.47$.Thus,the frequency of $B$ is $0.53$ and $b$ is $0.47$.

Genotypes	$BB$	$Bb$	$bb$
Frequency	$22\%$	$62\%$	$16\%$

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?
