What is an Ectomorph?

7. Sex and Inheritability

While females typically have higher body fat percentages than males, there is little research that indicates they are more likely to have a specific somatotype. Studies of athletes at various levels of competition even indicate the opposite. Sex appears to have very little if any effect on adult somatotypes. One study suggests that mothers can pass on their somatotype to their children, though additional research is necessary to confirm this.
