Question

question 3
a species of small lizard has three color forms: pale gray, brown, and black. in its original range, the colors of the rocky
environment were mixed from pale gray to very dark, and the population had an even mix of all three color forms. the
blending of colors with the environment helps the lizards hide from predators. a group of these lizards ended up on an
island with all gray rocks, and the island has no predators that eat lizards. what will the lizards look like in 50 years?
a mixture of all colors
b all pale gray
c all brown
d all black
e mixture grey and black only

Explanation:

In the original environment, color - blending helped lizards hide from predators. But on the new island with no lizard - eating predators, there is no selective pressure based on color. So, the genetic diversity (different color forms) will be maintained as there is no advantage or disadvantage for any particular color form.

Answer:

A. Mixture of all colors
