Tottenkoph gender and sex are not necessarily the same thing . Scientist refer to male female genetic differences as sex. Social and cultural differences are referred as gender.
I am perplexed by the many science deniers especially when it comes to global warming, vaccination and medical quackery.
gender
- either of the two sexes (male and female), especially when considered with reference to social and cultural differences rather than biological ones. The term is also used more broadly to denote a range of identities that do not correspond to established ideas of male and female.
