Question

If frequency of autosomal dominant allele is 0.6 then find out the number of members of recessive phenotype in a population of 6,000 member .

• A. 1200
• B. 4000
• C. 960
• D. 1000

Answer 1

The correct option is C 960

p=0.6
q=1-0.6=0.4
q =0.16
2 that implies in 100 individuals 16 are of recessive phenotype $\left(\frac{16}{100}\right)\times 6000=960$
Therefore,in 6000 individuals no.of recessive phenotypes.
