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 $= 0.2461$

he Punnett square shows the cross for a particular trait between a homozygous dominant parent and a heterozygous parent. What is

Crazy boy [7]

Answer:

50%

Explanation:

Let's make a Punnett square to represent this, with X representing our dominant allele and x our recessive.

One homozygous dominant parent = XX

One heterozygous parent = Xx

X X

X XX XX

x Xx Xx

So two out of our four outcomes are heterozygous for the trait. That means the answer is <u>B. 50%.</u>
