Question

in peas, a gene controls flower color such that r1 = purple and r2 = white. the purple allele is dominant to the white allele. in an isolated pea patch, there are 36 purple-flowering plants and 64 white-flowering plants.

assuming hardy-weinberg equilibrium,

q1: what is the value of q for this population?

q2: what is the percentage of heterozygous purple in this population?

please justify your answers to receive full credits.

Explanation:

Identify the given population parameters

Using the Hardy-Weinberg Equilibrium and Genotype Frequencies knowledge points

$$
LATEXBLOCK0
$$

Calculate the recessive allele frequency q

Using the Allele Frequencies knowledge point

$$
LATEXBLOCK1
$$

Calculate the dominant allele frequency p

Using the Allele Frequencies knowledge point

$$
LATEXBLOCK2
$$

Calculate the frequency and percentage of heterozygotes

Using the Hardy-Weinberg Equilibrium and Genotype Frequencies knowledge points

$$
LATEXBLOCK3
$$

Answer:

Question 1

\(q = 0.8\)

Question 2

\(32\%\)
