Short Answer

Expert verified
Short Answer: In such cases, it is suggested that the trait is more influenced by heredity.

Step by step solution

01

Understand the adoption study

Adoption studies are widely used in behavior genetics to determine the influence of heredity on specific traits. In these studies, researchers compare the similarity of adopted children to their biological and adoptive parents regarding certain traits. The goal is to see if there's a strong correlation between the child's traits and the traits of the biological parents or adoptive parents, which can provide insights into the role of heredity and environment in shaping an individual.
02

Identify the terms for the blanks

Based on the knowledge of adoption studies and the role of heredity, we can infer that the statement is highlighting the fact that heredity influences a trait if children adopted at a young age share more trait similarity with their biological parents than their adoptive parents. This is because a higher similarity between the child and the biological parents would suggest that the trait is more influenced by heredity, while a higher similarity between the child and adoptive parents would suggest that the trait is more influenced by the environment.
03

Fill in the blanks

Now that we know the correct terms to fill in the blanks, we can complete the statement: The findings from adoption studies suggest that heredity influences a trait if children adopted at a young age share more trait similarity with their biological parents than their adoptive parents.
