Question

Divide the contents of a large bag of different-colored candies randomly and approximately equally among the members of the group. Do not pick specific candy colors, but simply empty the contents of the bag onto a table and quickly divide the pile. If you are doing this exercise by yourself, divide the contents of the bag into five piles.

Identify what phenomenon explains the observed differences. What evolutionary mechanism do the observations emulate?

Accepted Answer

Hey, everyone. Let's take a look at this question together. A small group of birds may become isolated on an island and start a new population. If the new population has only a small subset of the alleles present in the original population, then the frequency of these alleles will be much higher in the new population. And it will lead to significant genetic differences between the new population and the original population. This phenomenon is referred to as what is it? Answer choice, a natural selection, answer choice B mutation, answer choice C gene flow or answer choice D bounder effect. Let's work this problem out together to try to figure out which of the following answer choices describes this phenomenon. So from the question, we know that we have a small group of birds that become i isolated on an island and start a new population. And since that small group of birds are starting a new population, that means that the small group of birds are considered founders in their new population since they are the first ones in their new population. And since the new population has only a small subset of the alleles that were present in the original population. It leads to genetic differences between the new population, which are those founders and the original population, which describes a type of genetic drift that is called the founder effect, which is answer choice. D the correct answer since the founder effect, which is a type of genetic drift occurs when a small group of individuals. In this case, we're talking about the small group of birds become isolated on an island and start a new population which leads to a change in the frequency of the alleles in that new population. So answer choice D founder effect is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
