Read DetailsThere is a flock of grouper fish (a type of coral reef fish species) living in the reef area near Costa Rica. There are three alleles (A1,A2,A3) for the fish scale reflection, making the fish having different colors and reflection (A1 for bright light color, A2 for dim light color, A3 for dim dark color). These colors and reflection Read the following scenarios, you need to answer two question for each scenario (a) predict how allele frequencies change, (b) identify the evolutionary mechanism. In your answer, please clearly indicate scenarios (1),(2). Failure to do so will lead to 0pt of this question. (1) Bigger sized predator fish present. The predator species is triggered by bright color. allele frequency change? evolutionary mechanism? (2) Anglers (like Prof. Wang) fishing at night in this area allele frequency change? evolutionary mechanism?
Read DetailsConsider the following statement about the Galapagos finches:”Finch species A evolved a narrow, pointed beak because it needed to eat insects, while finch species B evolved a large, crushing beak because it needed to crack tough seeds.” Which of the following provides the most complete and accurate biological critique of this statement?
