Little Johnny's father is incredibly organized, but his mother tends to be messy. When Little Johnny's aunt notices that all of his binders are labeled and his room is spotless, she claims "you obviously didn't inherit your mother's 'messy' genes!". What is wrong with this statement?
a. Nothing is wrong with this statement. Our behaviors, just as much as our physical characteristics, are inherited from our parents.
b. The organizational-skill gene is an X-linked gene; therefore, since Johnny is a boy, he only took after his mother.
c. This statement is incorrect because the son may actually have some of his mother's "messy" genes, too. The gene for organization is recessive.
d. Characteristics, such as organizational skills, are behavioral and environmentally influenced. Therefore, they are not specifically inherited.
e. The organizational-skill gene is Y-linked; therefore, that is why he is organized, like his father.
Ans: d. Characteristics, such as organizational skills, are behavioral and environmentally influenced. Therefore, they are not specifically inherited.
