Question

Quizplus · Accepted Answer

Clubfoot and cleft palate are both congenital birth defects, meaning that they are present at birth. They also have a discontinuous distribution, meaning that individuals either have the trait or they do not. These traits are multifactorial, meaning that their development is influenced by both genetic and environmental factors. The threshold model is the most commonly used model to explain the distribution of these traits, as it suggests that individuals with a certain number of risk factors are more likely to develop the trait. Therefore, all of the given characteristics apply to clubfoot and cleft palate.
