HARDY WEINBERG EQUILIBRIUM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If the frequency of two alleles in a gene pool is 90% A or p and 10% a or q, what is the frequency of individuals in the population with the genotype Aa or 2pq?
A
0.10
B
0.01
C
0.18
D
0.81
E
0.9
Explanation: 

Detailed explanation-1: -From this, We can compute the heterozygotes: 2pq = 2 (0.9) (0.1) = 0.18.

Detailed explanation-2: -We can calculate the values of p and q, in a representative sample of individuals from a population, by simply counting the alleles and dividing by the total number of alleles examined.

Detailed explanation-3: -In a Hardy Weinberg question, if they give you the # of Homozygous dominant, # of heterozygous and the # of homozygous recessive. You can calculate the p and q by using the total number of alleles of p or q divided by the total number of alleles in the population or finding
