Read the following scenario. Use the Hardy-Weinberg principle and your knowledge of natural selection to explain the scientists' logic. Provide your answer in two standard paragraphs (four or five sentences each) using complete sentences. Refer to the given scenario in your answer. In an isolated population of 1,000 white-tailed deer, about 850 deer possess long legs. The dominant allele for leg length is long legs, and deer that are homozygous for this dominant allele or are heterozygous possess long legs. The population mates randomly and is stable. Living in a forest, they feed mostly on shrubs and the low-hanging leaves and branches of understory trees. During the last 20 growing seasons, the shrub layer has slowly disappeared from the ecosystem. The population of deer adapted by foraging primarily on the leaves and branches of understory trees. Over browsing has occurred, and the understory trees have lost most of their leaves and tender shoots where the deer can access them.

Impacts of Natural Selection
Read the following scenario. Use the Hardy-Weinberg principle and your knowledge of natural selection to
explain the scientists' logic. Provide your answer in two standard paragraphs (four or five sentences each) using
complete sentences. Refer to the given scenario in your answer.
In an isolated population of 1,000 white-tailed deer, about 850 deer possess long legs. The dominant allele for
leg length is long legs, and deer that are homozygous for this dominant allele or are heterozygous possess
long legs. The population mates randomly and is stable. Living in a forest, they feed mostly on shrubs and the
low-hanging leaves and branches of understory trees
During the last 20 growing seasons, the shrub layer has slowly disappeared from the ecosystem. The
population of deer adapted by foraging primarily on the leaves and branches of understory trees. Over
browsing has occurred, and the understory trees have lost most of their leaves and tender shoots where the
deer can access them.
Scientists predict that in future years, more deer with long legs will be observed in the population.
