Question 20 You are studying a species of butterfly whose caterpillars produce different toxins based on the genotype of the Tox locus. Alleles E and N are codominant. Individuals homozygous for E are emetic (cause vomiting), while caterpillars homozygous for N produce a neurotoxin. Heterozygotic caterpillars produce a toxin with both qualities. At the Bocas del Toro research station in Panama, you counted 45 neurotoxic caterpillars, 57 emetic caterpillars, and 82 caterpillars with both toxic qualities. Using the Hardy-Weinberg equilibrium equation, you calculated the expected genotypic frequencies: NN= 0.218, NE= 0.498, EE= 0.284. Is this population in Hardy-Weinberg Equilibrium? Why/why not? A No, because the X^2 test statistic is greater than 3.84. B No, because the genotype frequencies not equal 1. Yes, because the X^2 test statistic is greater than 3.84. D Yes, because the genotype frequencies are approximately equal to 1. E) No, because the X^2 test statistic is less than 3.84. F) Yes, because the X^2 test statistic is less than 3.84.

You are studying a species of butterfly whose caterpillars produce different toxins based on the genotype of the Tox locus. Alleles E
and N are codominant. Individuals homozygous for E are emetic (cause vomiting), while caterpillars homozygous for N produce a
neurotoxin. Heterozygotic caterpillars produce a toxin with both qualities.
At the Bocas del Toro research station in Panama, you counted 45 neurotoxic caterpillars, 57 emetic caterpillars, and 82 caterpillars
with both toxic qualities. Using the Hardy-Weinberg equilibrium equation, you calculated the expected genotypic frequencies: NN=
0.218, NE= 0.498, EE= 0.284.
Is this population in Hardy-Weinberg Equilibrium? Why/why not?
A) No, because the X^2 test statistic is greater than 3.84.
B) No, because the genotype frequencies do not equal 1.
c) Yes, because the X^2 test statistic is greater than 3.84.
D Yes, because the genotype frequencies are approximately equal to 1.
E) No, because the X^2 test statistic is less than 3.84.
F) Yes, because the X^2 test statistic is less than 3.84.
