If a change occurs in gametes and helps survival why is it more important in evolution?
Answer and explanation
Correct answer: Because it can pass to offspring and increase through natural selection
The governing concept is heritable variation followed by natural selection. A change in a gamete can be transmitted to offspring because gametes carry genetic information. If the change improves survival or reproduction, individuals possessing it may leave more offspring, causing the trait to become more common over generations. Hence option A is correct; the other choices deny inheritance or confuse a genetic change with fossil formation.
