Most animals and plants reproduce sexually. this means that dna is passed down to new organisms from two parental organisms. which of the following is a key advantage of sexual reproduction?
a. the elimination of genetic mutations from a parent organism
b. increased genetic diversity for changing environments
c. the receipt of the strongest genes from both parents for survival
d. the creation of new genes to improve surviva

B. Increased genetic diversity for changing environments

With sexual reproduction an offspring gets a bit of traits from both parents. This means that there is more variety and diversity. Think about humans. We are very genetically divers. There are people with brown hair or blond or red. People with blue, brown, or green eyes. There are also some people that are short or tall. This goes to show that sexual reproduction increases genetic reproduction.

Hope this helped!
