Final answer:
Sexual reproduction is the form of reproduction that increases diversity within a population.
Step-by-step explanation:
Sexual reproduction is the form of reproduction that increases diversity within a population. During sexual reproduction, the genetic material from two individuals is combined to produce genetically diverse offspring. This diversity can enhance the survival of a population in a changing environment. For example, when conditions change, sexually produced offspring have a greater likelihood of possessing traits that allow them to adapt and survive.
