Question
Part A Use the following information to answer the question below. Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are determined (see chart) and used to determine the actual allele frequencies in the population. Allele Frequencies Tt 056 0.28 0.16 Refer to the accompanying figure. Is this population in HardyWeinberg equilibrium? O Yes No; there are more heterozygotes than expected No, there are more homozygotes than expected. It is impossible to tell. O Submit uest Ans Provide Feedback Next >Explanation / Answer
According to the figure, is this population in Hardy-Weinberg equilibrium?
C) No; there are more homozygotes than expected.
When we will do this then dont square p or q b/c (p^2) represents homozygous frequency that is already the same thing for q and 2pq (dont need to multiply by 2)
As we know, p + q = 1
So, take the square root of the genotype frequencies then add them, if greater than one then it does not meet equlibrium b/c indicates the more homozygotes than expected
as in this case
No; there are more homozygotes than expected.
