which best describes the relationship between genetic variation and adaptation? 1. individuals in a population are genetically different from one another. 2 individuals have different traits because they have different genes. 3 individuals with certain genes are more likely to survive and reproduce. 4 individuals change their genes so they are better suited to their environment.

Explanation:

Genetics are something that everyone (or only you) have. And adaptation is getting something from someone. Or Adapting to that.

Adaptations develop when certain variations or differences in a population help some members survive better than others . The variation may already exist within the population, but often the variation comes from a mutation, or a random change in an organism's genes.
