4. Cystic fibrosis is a homozygous recessive condition that affects 1 in 10,000 of the Hispanic population in the United States. Calculate the frequency of the dominant allele, the frequency of the recessive allele, and the percentage of heterozygous individuals (carriers) in the Hispanic population. Frequency of the dominant allele Frequency of the recessive allele % homozygous dominant % homozygous recessive % heterozygous

Expert Solution
Step 1

From the Hardy-Weinberg formula,

 

p2 + 2pq + q2 = 1

and p + q = 1

Here,

p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population
p2 = percentage of homozygous dominant 
q2 = percentage of homozygous recessive 
2pq = percentage of heterozygous
