1. A population of lizards in H-W equilibrium has two color variants. Green lizards (G) are dominant and blue lizards (g) are recessive. The frequency of G is 0.19, and the frequency of g is 0.81. Calculate the percentage of heterozygous individuals in this population. 2. A population of lizards in H-W equilibrium has two color variants. Green lizards (G) are dominant and blue lizards (g) are recessive. The frequency of G is 0.19, and the frequency of g is 0.81. Calculate the percentage of homozygous recessive individuals in this population.

Question

I need help with these four practice problems. 

Please show all your work to get the fll extra credit points!
H-W Equations
p2 + 2pq + q? = 1
p+q = 1
H-W Variables
p? = homozygous dominant genotype
2pq = heterozygous genotype
q? = homozygous recessive genotype
p = frequency of dominant allele
q = frequency of recessive allele
Practice Problems:
1. A population of lizards in H-W equilibrium has two color variants. Green lizards
(G) are dominant and blue lizards (g) are recessive. The frequency of G is 0.19,
and the frequency of g is 0.81. Calculate the percentage of heterozygous
individuals in this population.
2. A population of lizards in H-W equilibrium has two color variants. Green lizards
(G) are dominant and blue lizards (g) are recessive. The frequency of G is 0.19,
and the frequency of g is 0.81. Calculate the percentage of homozygous
recessive individuals in this population.
3. In a population that is in H-W equilibrium, the frequency of the homozygous
recessive genotype (aa) is 0.09. Calculate the percentage of individuals that are
homozygous for the dominant allele (AA).
4. In a population of rabbits in H-W equilibrium, white fur is dominant (W) and grey
fur (w) is recessive. A random sample of 100 rabbits from this population
contains 9 grey rabbits (ww) and 91 white rabbits. Calculate the frequencies of
the white and grey alleles in this sample.
