Question
The graphs below depict the weight classes of adopted children as compared to the body mass index (BMI) of their biological parents (left) or adoptive parents (right). What conclusions are supported by this data?
a. Adoptive fathers of obese children have a higher BMI than adoptive fathers of thin children.
b. Biological fathers of obese children have a higher BMI than biological fathers of thin children.
c. Adoptive mothers of obese children have a lower BMI than adoptive mothers of thin children.
d. Biological mothers of thin children have a lower BMI than the biological mothers of obese children.
e. Adoptive mothers of thin children have lower BMI than adoptive mothers of obese children.
Explanation / Answer
Option [b] Biological fathers of obese children have a higher BMI than biological father of thin children.
[d] Biological mothers of thin children have a lower BMI than the biological mothers of obese children.
However, this might not always be true but we can conclude this because although obesity is a lifestyle disease but sometimes it runs in a family and is inherited by children from their parents.
Adoptive parents have no genetic relationship with their adopted children.
