Question

How does natural selection change the frequency of genes or traits over many generations? Biology students conducted an experiment mimicking genetic variation and coloration. Students used different colored beans to represent animals that might be prey: mice, for example. A student in each group was the predator: a hawk. Beans (mice) were randomly scattered on multicolored floor tiles, each color within four tiles. The hawk collected mice (beans) for 10 seconds. Mice not eaten reproduced. Three generations of data a shown in the table. Speckled and striped beans (mice) had the best survival rates. Why?
A) They reproduced very rapidly.
B) Coloration was a form of camouflage.
C) They mimicked other mice and were spared.
D) The speckled and striped beans had a wider range.

Answer 1

B)Coloration was a form of camouflage. If they were not eaten they reproduced then they were not eaten because they were camouflaged. And so on. Hope this helps!!

Answer 2

Answer is: B) Coloration was a form of camouflage.

This is example of natural selection and adaptation.

Predators will easily capture mice with different colors and their population will drope, exception are striped mice because they are better hidden because of camouflage.

Genetic variation is important to the population's ability to survive in different situations that affect natural selection.

The environment is constantly changing and different alleles are favored.

An increase in predator will decrease genetic variation in a population of mice.
