Question

Quizplus · Accepted Answer

Todd's significant difference in height from his family, who are all over six feet tall, suggests an external factor influenced his growth. An early childhood illness could have affected his growth hormones or development, leading to his shorter stature. Genetic factors (A) are less likely since his entire family is tall, and genotype normalization (D) doesn't directly explain a single individual's deviation from family traits. A sedentary lifestyle (C) typically does not result in such a drastic difference in height, especially when compared to genetic relatives.
