Dr. L. Hill conducted a study examining music ability in families; she recorded the concordance rates of music ability of adopted children and their parents (who raised them), and she also recorded the concordance rates of the children with their biological parents. Then, she compared the two sets of concordance rates. Dr. Hill is studying: Selected Correct Behavior genetics Answers: A. Dominant-recessive B. gene relationships C. Correct Behavior genetics D. Epigenesis Active gene effects

Option C, Correct Behavior genetics

Explanation:

Behaviour genetics is the study of the influence of both genes and environment on the behaviour of an individual. This study is done to understand how both genes and environment together affect the behaviour of an individual. It is believed that all forms of behaviors are either inherited or learned. Mr. Hill is noting the concordance rates of music ability  for both biological children (who might have inherited this ability from their parents) and adopted children (who might have learned this ability from the musical environment around them)

Hence, option C is correct

there really is life in the deepest part

a physical change is being made.
