of shares in S&P 500 companies in 2020, compared with an estimated $9 billion for female executives.” This means women have significantly less influence on a company’s decision-making process as approximately 99 percent of the decision-making power is held by men. This is what they refer to as the Gender power gap. At home Gender roles in parenting and marriage Gender roles are heavily influenced by biology, with male-female play styles correlating with sex hormones, sexual orientation, aggressive traits, and pain. Furthermore, females with congenital adrenal hyperplasia demonstrate increased masculinity and it has been shown that rhesus macaque children exhibit preferences for stereotypically male and female toys.
