In a population of rats,the relative fitness and frequencies of genotypes at present are: $$\begin{array} { l l l }
& \text { Frequency } & \text { Fitness } \
H H & 0.4 & 1 \
H h & 0.5 & 0.8 \
h h & 0.1 & 0.6
\end{array}$$
What will be the frequency of the h allele in the next generation?

Question

In a population of rats,the relative fitness and frequencies of genotypes at present are: $$\begin{array} { l l l } 
& \text { Frequency } & \text { Fitness } \
H H & 0.4 & 1 \
H h & 0.5 & 0.8 \
h h & 0.1 & 0.6
\end{array}$$ 
What will be the frequency of the h allele in the next generation?

Quizplus · Accepted Answer

The frequency of the h allele in the next generation can be calculated using the Hardy-Weinberg equation:p^2 + 2pq + q^2 = 1where p is the frequency of the H allele and q is the frequency of the h allele.We know that the frequency of the H allele is 0.4 and the frequency of the Hh genotype is 0.5. Therefore, the frequency of the h allele is:q = 1 - p = 1 - 0.4 = 0.6Therefore, the frequency of the h allele in the next generation will be 0.6.
