• Peppered mohs vary from light to dark and the frequence of light and dark morths varies depending on the color of the trees in their environment.
,
• D. Natural selection. ,The color frequency is related to the trees because whe the moths are a different color from th trees, they are more easuily eaten, so o,nly the mmore adapted moths, ,survive, and have ,offspring,.
• A group of birds moves to a new patch of forest and begins to breed with the existing poplation that currently lives in that forest.
,
• B. Migration. , The group that arrives at the new patch of forest has, moved or migrated, and brings ,new genetic information, to the population living there previously.
• A small group of whte-tailed deer croosses the frozen water of Lake Michigan and establishes a new population on a remote island. The alleles present in the gene pol of the pfounder population differ from the populationpresent in the rst of Michigan. A
,
• A. Genetic drift ,(founder effect)., When a small grup o indviduals splts from the main population and sestablishes anew new one, this new popultion hasjust a s ,smallample of the alleles f,rom ththe original population, and just by, random chance(genetic drift), differetnt ,alleles will be fixated, in the new population
• Colorful lizards living on brown leaves are most often eaten by predators.
,
• D. Natural selection. ,As with the moths, the lizards with a more different color than their environment are moe prone to be eaten, so they don't reproduce and those colors don't remain in the poulation.
