<u>Answer:</u>

<em>B. Many genetic diseases would be curable. </em>

<u>Explanation:</u>

Gene therapy is intended to acquaint hereditary material into cells in order to compensate for faulty or mutated genes or to make a helpful protein. On the off chance that a faulty gene makes a beneficial protein be flawed or missing, gene therapy might have the option to present a typical duplicate of the gene to reestablish the function of the protein.  

A gene that is embedded straightforwardly into a cell as a rule doesn't work. Rather, a bearer or carrier called as a vector is hereditary built to insert the desired gene.

The gene frequency for a dominant allele is 0.68 and the recessive allele is 0.39. What percent of the population has a homozygo
Alinara [238K]

Answer:

15.21 %

Explanation:

If we recall the basic formula of Hardy-Weinberg's equilibrium ; we have the following below:

p + q = 1

p² + 2pq + q² = 1

where;

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p² = percentage of homozygous dominant individuals

q² = percentage of homozygous recessive individuals

2pq = percentage of heterozygous individuals

Given that p= 0.68 and q = 0.39

the percentage of the homozygous recessive genotype (q² ) will be

(0.39)² = 0.1521

= 0.1521 × 100

= 15.21 %

∴ the percentage of the population that has a homozygous recessive genotype = 15.21 %
