Psychologists use what to determine the role that heredity and the environment play in determining trait?
Psychologists like to use sets of identical twins for studies. If the identical twins turn out more similar than fraternal twins or regular siblings, they conclude that the trait is genetically influenced and hereditary.
What is the meaning of detached earlobes?
Detached earlobes refer to earlobes that hang freely and are not connected to the side of the head. This trait is a genetic variation, with earlobe shape being influenced by heredity. Detached earlobes are often considered a dominant trait, meaning they can be passed down from one generation to the next. In contrast, attached earlobes are connected directly to the head without a free-hanging section.

What refers to having identical alleles for a trait?
