Recommendation for a good, simple book on the science of gender

[HelpImSurrounded]

Can anybody recommend a book on the science of gender as simple as Bill Nye's recent Episode on the subject.

If we can identify a good, simple at a level that Marjorie Taylor Green can understand, we should all send her copies of it.

Her sign says "Trust the science", I agree with that but first she has to learn the science.

1. Gender or sex?

They are not the same.

2. Gender. As her sign says. Definitely gender.

3. The Second Sex, Volume 2

"Gender" isn't covered by a hard science. It's a societal construct. "One is not born, but rather becomes, a woman"

4. "simple at a level that Marjorie Taylor Green can understand,"

"simple at a level that Marjorie Taylor Green can understand," hmm. Does the Dick and Jane series of books tackle transgender issues?
