1. Why is genetic diversity within a population important? A. It gives organisms fewer options for mates

B. It allows populations to be more successful and not get diseases

I think its a , but double check because i dont want it to be wrong .

The correct answer is B

Genetic diversity allows for the organisms to have different genes that may ultimately lead to the ability to not be able to get diseases that might kill some of the organisms who don't have the gene.
