Question

Quizplus · Accepted Answer

Height is a trait with high heritability, meaning that genes play a significant role in determining a person's height. However, it is important to note that environmental factors such as nutrition can also influence height. Genes establish the range of heights a person may achieve, but other factors may impact where within that range they fall. Therefore, option D is the most accurate statement. Option A is incorrect because while genes do play a role in determining height, there is not a single gene that dictates a precise height. Option B is also incorrect because while ancestry can be a predictor of height, it is not a guarantee, as height is influenced by many factors beyond genetics. Option C is false because environmental factors such as diet and overall health can influence a person's height.
