Natural Selection and Candy Experiment

The video tutorial demonstrates how natural selection affects a population over generations using a candy model. The experiment involves candies with different colors representing genetic traits and predators that select based on visibility. The process shows how the frequency of traits changes due to selective pressures, illustrating microevolution. The tutorial concludes with a discussion on the mechanisms of evolution, emphasizing natural selection.

What is the primary purpose of using Rec's pieces candies in the experiment?

• To show how candies are made

• To illustrate the process of photosynthesis

• To demonstrate the concept of natural selection

• To explain the lifecycle of insects

In the experiment, what role do the predators play?

• They protect the candies from harm

• They change the color of the candies

• They select candies based on color visibility

• They help the candies reproduce

What is the initial allele frequency setup in the experiment?

• Half are orange and half are yellow

• There are no candies

• All candies are orange

• All candies are yellow

How does the environment affect the visibility of the candies to predators?

• The environment changes the color of the candies

• The environment has no effect on visibility

• The yellow environment makes yellow candies less visible

• The orange environment makes orange candies less visible

What happens to the population of candies after each night?

• The candies change color

• The candies reproduce asexually, doubling in number

• The candies migrate to a new environment

• The candies are eaten by predators

What is the significance of the predators using eyesight in the experiment?

• It allows them to reproduce with the candies

• It helps them protect the candies

• It enables them to select candies based on color

• It allows them to change the color of the candies

What is the result of the predators' selection over several generations?

• The population shifts towards more orange candies

• The population remains unchanged

• The population becomes extinct

• The population becomes more diverse

What concept is demonstrated by the change in allele frequencies in the candy population?

• Speciation

• Macroevolution

• Microevolution

• Genetic mutation

Which mechanism of evolution is primarily illustrated in this experiment?

• Gene flow

• Mutation

• Genetic drift

• Natural selection

Why do the orange candies tend to survive longer in the experiment?

• They reproduce faster

• They are more nutritious

• They blend in with the environment

• They are less tasty to predators
