The table shows the risk of inheriting the genetic disorder cystic fibrosis across different ethnic populations.   Cystic fibrosis is a genetic disorder that is caused by the cystic fibrosis transmembrane conductance regulator (CFTR) mutation. A person with one mutation is considered a carrier, but if a child inherits two mutations, the disease will be expressed. Based on the risk values in the table and assuming these populations are in Hardy-Weinberg equilibrium, how does the frequency of recessive allele in the Caucasian population compare to the frequency of the recessive allele in the Asian population?

The table shows the risk of inheriting the genetic disorder cystic fibrosis across different ethnic populations.

 

Cystic fibrosis is a genetic disorder that is caused by the cystic fibrosis transmembrane conductance regulator (CFTR) mutation. A person with one mutation is considered a carrier, but if a child inherits two mutations, the disease will be expressed. Based on the risk values in the table and assuming these populations are in Hardy-Weinberg equilibrium, how does the frequency of recessive allele in the Caucasian population compare to the frequency of the recessive allele in the Asian population?
