Question 2
The allele frequencies for a population are A = 0.6 and a = 0.4. Conditions change and fitness values are now AA = 0.3, Aa = 0.7 and aa = 1.0. What is the allele frequency of A in the next generation?
A. 
between 0.6 and 0.7 

B. 
between 0.5 and 0.6 

C. 
between 0.4 and 0.5 

D. 
0.6 

E. 
between 0.3 and 0.4 
Question 7
A gene exists in two alleles designated P and p. If 65 copies of this gene are the P allele and 140 are the p allele, what is the allele frequency of P?
a. 
0.16 

b. 
0.46 

c. 
0.32 

d. 
0.64 
2. The allele A can exist in homozygous (AA) as well as heterozygous (Aa) form.
So the frequency of A will be = frequency of AA + 1/2 frequency of Aa
= 0.3 + 1/2 x 0.7 = 0.3 +0.35
= 0.65
Therefore the correct option is A between 0.6 and 0.7
7. Copies of gene with P allele in a population= 65
Copies of gene with p allele= 140
Total copies of gene= 140+65= 205
Allele frequency= No. of copies of gene with the particular allele/total no of copies of gene
Allele frequency of P= 65/205= 0.32
