Suppose the human trait for hair type is controlled by a simple dominant and recessive relationship at one locus. Curly hair, C,
Zepler [3.9K]

Answer:

The frequency of the dominant allele, C = 0.2234

and the heterozygous genotype, Cc= 0.1736

Explanation:

Given -  

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

Thus, C is dominant over c

The genotype frequency of curly hair is 52 in 131 students

so, remaining 131-52 = 79 are straight hair students.  

Since straight hair is a recessive allele , the genotypic frequency of "cc" is  

\frac{79}{131}\\0.6030

Frequency of "cc" is represented by q^{2}

Thus frequency of allele "q"  

= \sqrt{0.6030} \\= 0.7765

As per Hardy Weinberg's I equation -  

p+q=1\\p + 0.7765=1\\p = 0.2234

As per Hardy Weinberg's II equation -  

p^{2} +2pq + q^{2} =1\\0.2234^2+2pq+0.6030=1\\2pq= 0.1736

Hence,  

The frequency of the dominant allele, C = 0.2234

and the heterozygous genotype, Cc= 0.1736

State three examples of human activities that could endanger botana curus
statuscvo [17]

Botana curus is a plant that produces curus which is a substance that is used to cure different kind of cancer.

This is an endangered species that cannot be grown in the laboratory. The ability to produce curus in the laboratory is not feasible.

The human activities that could have endangered botana curus is:

Pollution: It lead to slow down the rate of growth of the plant.

Overexploitation: The over use of plant for its medicinal purpose.

Habitat: The natural habitat of the plant has been changed due to various human activities.
