Based on these data, what conclusions could the researchers make? a. Directional selection will push the entire population to have yellow shells. b. Yellow-brown snails are better adapted to their environment than the other colors because they match all types of backgrounds c. Stabilizing selection is occurring, creating a higher percentage of heterozygous individuals in each generation. d. There was higher mortality in yellow-brown snails than in brown or yellow snails.

After seeing the results for the observed and expected genotype frequencies, the researchers hypothesized there must be differences in survival rates for juvenile snails of different colors. They collected more data, and their results are shown in the figures below: 0.8 2501 200- 150 - 100 - 0.2 0.0 -1.5 -1.0 -0.5 0.0 0.5 1.0 -1.5 -1.0 -0.5 0.0 0.5 1.0 1.5 Shell Colour Shell Colour Figure 1 (left). Frequency of brown, yellow-brown and yellow shells found in a sample of adult land snails on Niijima Island. Figure 2 (right). Survival rates of snails with brown, yellow-brown, and yellow snails on Niijima Island, Japan. The dashed and solid lines are different measurements of survival rate. Q4. Based on these data, what conclusions could the researchers make? a. Directional selection will push the entire population to have yellow shells. b. Yellow-brown snails are better adapted to their environment than the other colors because they match all types of backgrounds c. Stabilizing selection is occurring, creating a higher percentage of heterozygous individuals in each generation. d. There was higher mortality in yellow-brown snails than in brown or yellow snails.
