Multiple Choice

Figure 25.1.
Use the following information when answering the following question(s) .
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.

-Refer to Figure 25.1.Is this population in Hardy-Weinberg equilibrium?

• A)Yes.
• B)No;there are more heterozygotes than expected.
• C)No;there are more homozygotes than expected.
• D)More information is needed to answer this question.
