In a random mating population frequency of dominant allele is 0.7. What will be the frequency of recessive organism?
Text Solution
Verified by ExpertsThe correct answer is:
B
It is given that,
the population frequency of dominant allele (p) is 0.7.
Hence, the population frequency of recessive allele (q) will be 
.
We know that,
,
where 
is frequency of homozygous dominant phenotype,
2 pq is frequency of heterozygous dominant phenotype, 
is frequency of homozygous recessive phenotype.
Hence, frequency of homozygous recessive phenotype 
will be 
.
