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 $B b(50 \%)=16+31=47 \%$
Organic evolution would have not been taken place
What is founder effect ?
Which one of the following factors will not affect the Hardy-Weinberg equilibrium?
Random unidirectional change in allele frequencies that occurs by chance in all populations and especially in small populations is known as
Factor affecting the Hardy-Weinberg principlesare
$(I)$ Gene flow ;
$(II)$ Genetic drift
$(III)$ Mutation
$(IV)$ Genetic recombination
$(V)$ Natural selection
The correct combination is
