If there are 19 plants with rough seeds in a population of 100, what is the allele frequency for smooth seeds?

%

Explanation:

Given,

Number of plants with rough seed

Total number of plants

Genotype frequency for "plant with rough seed" i.e

So the allele frequency for "rough seed"

As per Hardy weinberg equation, we know that sum of allele frequencies around the locus is equal to one .

Thus,

Substituting the value of q in above equation, we get -

%

p represent the frequency of smooth seed.
