The presence of freckles is due to a dominant allele. Four percent of the individuals in a particular population lack freckles. Use the Hardy-Weinberg formula to calculate the percentage of individuals in this population who are homozygous dominant for freckles.
a) 32%
b) 80%
c) 64%
d) 20%
e) 4%

Option C

Explanation:

Allele for dominant freckle trait is "F"

Allele for recessive no freckle trait is "f"

Given -

Population lacking freckles  %

As per Hardy Weinberg's equilibrium equation

p represents the frequency of dominant allele in a given population and represents the frequency of dominant individuals in a given population

Like wise

q  represents the frequency of recessive allele in a given population and represents the frequency of recessive individuals in a given population

Frequency of dominant allele

Frequency of homozygous recessive individual

Frequency of homozygous dominant individual

Option C is correct

the endomembrane system i think

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
