Cystic fibrosis occurs 1 in every 2,500 individuals.
Using Hardy Weinberg principle,
freq. of recessive allele/ q2 = 1/2500 = 0.0004
Take the square root,
q = 0.02
freq. of dominant allele/ p = q - 1
p = 0.98
freq. of heterozygous individuals = 2pq = 0.04

Therefore, the answer is 0.04, which is C.

Alex

Answer: B. Melting temperatures of primer should be between 55-80 degree Celsius.

Explanation:

Bacause the melting temperature controls the binding of the primers to your template DNA. At melting temperature 50% of the primer molecules are bound to their corresponding target sequence. If the difference in melting temperature between the two primers is too high, it might be difficult to find experimental conditions where both primers can bind to their target.
