Question

Quizplus · Accepted Answer

Boys and girls have similar height until around the age of 11, at which point boys tend to experience a longer growth spurt than girls. This gives boys more time to achieve greater height, resulting in an average height difference between genders. Factors like genetics, nutrition, exercise, and other environmental factors can also play a role in determining height, but the delay in puberty and longer growth spurt is the primary reason for the disparity in height between boys and girls.
