Based on the frequency for the normal-size allele, the percentage of normal sized rats is 92.16%.
Alleles are alternate copies of a particular which produce varied phenotypes.
The allele frequency is the frequency at which a particular allele occurs in a population.
Alleles are either dominant, recessive, or co-dominant.
In the given scenario, the allele for normal size in rats is dominant.
Assuming that the allele for size in rats is given as R and r.
According to the Hardy-Weinberg equilibrium equation;
If R = 0.72, r = 0.28
The percentage of normal sized rats is given as;
The percentage of normal sized rats = 2 * 0.72 * 0.28 + 0.72²
The percentage of normal sized rats = 0.9216
Therefore, the percentage of normal sized rats is 92.16%
In conclusion, the allele frequency helps us to calculate the percentage of the rats are normal sized.
