Question

Through advanced genetic screening, Todd was informed that he had the genetic potential to grow to 6'5. However, at age 35, Todd stands at about 5'10. Taking into account gene/environment interactions, how is this scenario best explained?

A) Todd's genetic potential was inaccurate.
B) Todd's environment played a significant role in his height.
C) Todd's genetic potential changed over time.
D) Todd's height is solely determined by genetics.

Answer 1

Todd's actual height of 5'10" compared to his genetic potential of 6'5" indicates that environmental factors played a crucial role in his growth, affirming the significant impact of gene/environment interactions on physical development.

Step-by-step explanation:

Through advanced genetic screening, Todd was informed that he had the genetic potential to grow to 6'5". However, at age 35, Todd stands at about 5'10". Taking into account gene/environment interactions, the scenario is best explained by option B) Todd's environment played a significant role in his height. Genes provide a blueprint for potential development, but environmental factors such as nutrition, health, or possibly endocrine system issues during growth years significantly impact whether an individual will achieve their full genetic height potential.

Thus, while Todd's genetic potential might have allowed him to reach 6'5", environmental factors throughout his life, such as his diet, overall health, and access to healthcare, among others, were integral in determining his adult height.
