The frequency of carriers for a rare autosomal recessive genetic condition is 0.04 in a population. Assuming this population is

dem82 [27]

Answer:

Option E, Not enough information is provided.

Explanation:

Given

Frequency of carriers for a rare autosomal recessive genetic condition $= 0.04$

As per Hardy Weinberg's principles, frequency of carriers is represented by $2pq$

The second equation of Hardy Weinberg's principle states that -

$p^{2} + q^{2} + 2pq=1$

Thus, we have only one component i.e $2pq$ and no other values of p or q. Thus, the information provided is not sufficient to solve the question.

Option E, Not enough information is provided.
