Gender, School, Society and Inclusive School has a fabulous and very detained explanation of the difference between sex and gender in the first section.

Parental Expectations for Young Children [http://www.tandfonline.com/doi/abs/10.1080/0300443920790105] finds that both mothers and fathers expect girls to be more artistic and more compliant/obedient (!!!) than boys.
