Explain how natural selection could lead to a change in allele frequency leading to a change in the color of the frogs.
Pie

Answer:

Due to increasing the survival.

Explanation:

The natural selection causes a change in allele frequency leading to a change in the color of the frogs because the colour of the frog helps it in hiding from predators. The population of that frog specie increases which has the ability to hide from the predators in that environment while on the other hand, the population of frog decreases which can easily be seen by the predator due to its colour so this change in allele frequency will leads to natural selection.

Although the specie can walk on land but the finding characterized the creature primarily as a fish.
