The presence of: a prostate a penis breast development at puberty descended testes pubic and axillary hairarrow_forwardOn what assumptions Ratio of Males to Females in Humans is determined ?arrow_forwardBoth men and women produce testosterone, but concentrations of testosterone in the blood are generally higher in men than in women. However, the testosterone levels of some XX females fall within the range of testosterone levels of XY men. This overlap has created controversy within women’s sports. Testosterone is known to increase muscle mass and enhance some types of athletic performance, so some people have suggested that women with naturally high testosterone levels have an unfair competitive advantage. In 2011, the International Association of Athletics Federations (IAAF) adopted a policy that limits levels of testosterone in female athletes, saying that female athletes must not have a blood testosterone concentration greater than 10 nanomoles per liter (nmol/L), a level typically seen in men. Some elite female athletes have natural testosterone levels above this limit and have challenged the policy. Do you think that it is fair for XX females with naturally high testosterone…arrow_forward

Explain how chromosomes influence the internal and outward development of the sexual anatomy (hormones and structures). Is there always a correlation between genetic and anatomical sex? What is the reason, or why not? Describe a situation or disorder in which the internal and exterior sexual anatomy of a person do not match and explain how this would occur.
