Question

In a population where cystic fibrosis is caused by a defective CFTR protein encoded by the recessive allele f, and individuals with at least one wild-type allele do not develop symptoms of cystic fibrosis, calculate the relative fitnesses for the following genotypes:

A) Homozygotes for the wild-type allele (FF)
B) Heterozygotes (Ff)
C) Homozygotes for the recessive allele (ff)
D) Insufficient information to determine

A) 1.0, B) 0.85, C) 0.70, D) 1.0
A) 1.0, B) 1.0, C) 0.70, D) 0.85
A) 0.85, B) 1.0, C) 0.70, D) 1.0
A) 1.0, B) 0.85, C) 1.0, D) 0.70

Answer 1

The relative fitnesses for different genotypes in a population with cystic fibrosis are provided.

Step-by-step explanation:

In a population where cystic fibrosis is caused by a defective CFTR protein encoded by the recessive allele f, the relative fitnesses for the following genotypes are:

A) Homozygotes for the wild-type allele (FF) have a fitness of 1.0.

B) Heterozygotes (Ff) have a fitness of 0.85.

C) Homozygotes for the recessive allele (ff) have a fitness of 0.70.

D) Insufficient information to determine the fitness is given.
