Question

In a population of humans, the frequency of straight hair is 34 percent. If straight hair is the recessive phenotype, what is the frequency of the homozygous recessive genotype? 17 percent 34 percent 66 percent 68 percent

Answer 1

It's a recessive trait, which only expresses when the genotype is homozygous so....
34% straight hair = 34% homozygous recessive genotype.

Answer 2

Answer:

The correct answer would be 34 percent.

As the straight hair is a recessive trait, thus, the genotype of the people with straight hair phenotype would be homozygous recessive.

Hence, the frequency of individual with straight hair would be the same as that of an individual with homozygous recessive genotype.

So, the frequency of individuals with homozygous recessive genotype would be 34 percent.
