Populations with are more likely to survive in different environments.
a. more females than males
b. much genetic diversity
c. large populations
d. little genetic diversity

b. much genetic diversity

Explanation:

Genetic diversity gives the opportunity to societies to be able to adapt to different environments, this is very important because different genes thrive on different environments, so a population that has gene diversity can help its members to survive, for example think of the migration of fishes, if the population of those fishes can´t withstand cold waters if they arrive to cooler parts of the ocean they will all perish, but if you have different genes that withstand and that do not do it, those who can withstand the cold waters can survive and teh population survives.
