Sex distinct from gender

"As an instructor of gender and women's studies, I often challenge my
students about what in life is or is not "gendered." Can they, I
ask, tell the difference between a biological male's writing versus
a biological female's? Assuring me that they can, I present to them
three separate pictures, and I ask them to write a short story about
each picture. Then, I read them aloud, and students try to identify
if it is a female author or a male one. We then discuss the
"results," and the class sees that they were correct about 50
percent of the time. Which is exactly about right.
I then ask students what else they think is gendered-objects,
expectations, performances. People?"
