Answer:
0.150
Explanation:
Frequency of the recessive mystery disease in the population= 1/148= 0.0067
This means that the frequency of homozygous recessive genotype in the population= 0.0067
Therefore, the frequency of the recessive allele in the population= square root of 0.0067= 0.0818
Since the population is in Hardy-Weinberg equilibrium, frequency of the dominant allele in the population= 1-frequency of recessive allele= 1-0.0818= 0.918
Therefore, the frequency of heterozygous carrier genotypes in the population= 2 x frequency of dominant allele x frequency of recessive allele= 2 x 0.0818 x 0.918= 0.150
