Which of the following scenarios describing parents Luke and Laura would serve as an example of assortative mating--a potential problem associated with twin estimates of heritability?

Assortative mating refers to the phenomenon where individuals with similar phenotypic traits are more likely to mate with each other than by chance. This can include similarities in education level (A), socioeconomic status (B), and behavioral traits such as aggression (C). Therefore, all the scenarios (A, B, and C) exemplify assortative mating, which can complicate the interpretation of twin studies on heritability by increasing the genetic similarity of parents, potentially inflating heritability estimates.
