If the frequency of an autosomal dominant allele is 0.6. Calculate the frequency of recessive phenotype in a population of 10,000.

The correct option is A 1600
P = 0.6
q = 1 - 0.6 = 0.4
This implies that, in 100 individuals, 16 are of recessive phenotype. Therefore in 10,000 individuals, number of recessive phenotype
$\left(\frac{16}{100}\right)\times 10,000=1600$
