Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Some rattlesnakes in a population have markings that help the snakes hide. The snakes with these markings catch more prey, live longer, and have more offspring than the other snakes. What does the theory of natural selection predict about this population?
A
It will not change.
B
It will become extinct.
C
Over time, more members will have the useful markings.
D
Over time, fewer members will have the useful markings.
Explanation: 

Detailed explanation-1: -In natural selection, genetic mutations that are beneficial to an individual’s survival are passed on through reproduction. This results in a new generation of organisms that are more likely to survive to reproduce.

Detailed explanation-2: -In the theory of natural selection, organisms produce more offspring than are able to survive in their environment. Those that are better physically equipped to survive, grow to maturity, and reproduce.

Detailed explanation-3: -So, the correct answer is ‘Individuals with the most favorable traits survive and reproduce’

Detailed explanation-4: -Q. What is the most likely result if two populations of the same species are separated for a long period of time? Both populations will change in the same ways.
