select the best answer for the question.

1. 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 creation of new genes to improve survival
b. the receipt of the strongest genes from both parents for survival
c. the elimination of genetic mutations from a parent organism
d. increased genetic diversity for changing environments
mark for review (will be highlighted on the review page)

Explanation:

• Option A: Sexual reproduction doesn't create new genes; it combines existing genetic material. So A is incorrect.
• Option B: Offspring get a mix of genes from parents, not necessarily the "strongest" in a simple way, and this isn't the key advantage. So B is incorrect.
• Option C: Sexual reproduction doesn't eliminate genetic mutations from parents; mutations can still be passed on. So C is incorrect.
• Option D: Sexual reproduction involves the combination of genetic material from two parents, leading to increased genetic diversity. This diversity helps species adapt to changing environments, which is a key advantage.

Answer:

D. Increased genetic diversity for changing environments
