Quizplus · Accepted Answer

Height is a heritable trait, meaning that it is determined in part by genetics. Studies have shown that there is a positive correlation between the heights of fathers and their sons, but this correlation is not perfect. Based on this, the correlation between the fathers' heights and the heights of their 16-year-old sons is most likely to be near +0.7, indicating a strong positive relationship, but not a perfect one.
