Consider a gene that where a disease-causing low-frequency recessive allele is segregating in the population. This would
be similar to the case of cystic fibrosis.
Assume standard genetic nomenclature where the wildtype allele occurs at frequency p and the disease-allele occurs at
frequency q.
What is the correct calculation to find the probability that a single healthy individual is a carrier for the disease allele?
(Hint: You want the chance of being a heterozygote divided by the chance of being a healthy person)
p? + q?
p- 4
(1-q?)/2pq
2pq/(1-q²)
q°/2pq
