Question

A fungus that is predator of a species of frog have killed 50 frogs to save this species of frog scientist set other 35 frog to a different area then tell which process will save this type of frog species?

• A. Bottle neck effect
• B. Founder effect
• C. Big bang theory
• D. Natural selection

Answer 1

The correct option is A Bottle neck effect

A- Population bottlenecks occur when a population's size is reduced for at least one generation. Because genetic drift acts more quickly to reduce genetic variation in small populations, undergoing a bottleneck can reduce a population's genetic variation by a lot, even if the bottleneck doesn't last for very many generations.

B- A founder effect occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have:

• reduced genetic variation from the original population.
• a non-random sample of the genes in the original population.

So, the correct option is 'Option A'.
