There is no significant relationship between later development and height in boys. In medicine, the most significant factor affecting the height of a child or children is genetic. The heritability of height can reach 70-90%, while the influence of girls may be even greater, with a heritability rate of 85%-92%. 75%-92% of boys’ height and 85%-92% of girls’ height is influenced by heredity. With 25% of males and 15% of females depending on acquired factors, heredity plays an extremely important role in the height of children. Weight, on the other hand, is less influenced by heredity, 63% for males and 42% for females. Nutritional status, physical activity, surroundings, and lifestyle habits are all factors that affect height, but the main factor that affects height is genetics.
