4 Multiple Choice 20 points Rio Grande leopard frogs grow from 2.2 to 4.5 inches in length.Theyare usually tan brown,or pale green in color, with distinctive thack spotting and prominent light-colored ridges down either side of their backs. After a flash flood event, therewerevery few pale green frogs left in the population.After several generations ,pale green leopard frogs are virtually norrevistent. Which evolutionary process decline in pale green leopard frogs? Muations Natural Selection Gene Flow Genetic Drift

## Step 1<br />The problem presents a scenario where the population of pale green leopard frogs has drastically decreased after a flash flood event. The question asks us to identify the evolutionary process that has led to this decline.<br /><br />## Step 2<br />The options provided are: Mutations, Natural Selection, Gene Flow, and Genetic Drift. We need to understand what each of these terms means in the context of evolution.<br /><br />## Step 3<br />Mutations refer to changes in the DNA sequence of an organism. While mutations can lead to changes in an organism's traits, they do not explain the selective decrease in a specific trait.<br /><br />## Step 4<br />Natural Selection is a process where organisms that are better adapted to their environment tend to survive and produce more offspring. This process can lead to the decline of certain traits if they are not advantageous for survival.<br /><br />## Step 5<br />Gene Flow refers to the transfer of genetic variation from one population to another. This process does not explain the selective decrease in a specific trait.<br /><br />## Step 6<br />Genetic Drift is a process where the frequency of a trait in a population changes due to random chance. This process does not explain the selective decrease in a specific trait.<br /><br />## Step 7<br />In this case, the pale green color of the leopard frogs may have made them less visible to predators during the flash flood event, leading to their decline. This is an example of natural selection, where the environment (in this case, the flash flood) has selected against the pale green color.
