Suppose the human trait for hair type is controlled by a simple dominant and recessive relationship at one locus. Curly hair, C,
myrzilka [38]

Answer:

A) The frequency of the dominant allele, C = 0.4376

B) frequency of the heterozygous genotype, Cc = 0.2461

Explanation:

Given -

Curly hair, C, is the dominant allele, and straight hair, c, is the recessive allele

Number of students with curly hair is 37

Thus frequency of genotype "CC"

= q^{2} = \frac{37}{117} \\= 0.3162

Thus, frequency of allele "q"

= \sqrt{0.3162} \\= 0.5623

As per Hardy Weinberg's first  equation-

p+q=1

Substituting the value of q, we get -

p+0.5623=1\\p= 0.4376

As per Hardy Weinberg's second equation -

p^2+q^2+2pq=1\\

Substituting the values of "p" and "q" we get -

0.4376^{2} + 0.3162+2pq = 1\\2pq = 0.2461\\

Hence,

A) The frequency of the dominant allele, C = 0.4376

B) frequency of the heterozygous genotype, Cc = 0.2461
