This question was part of a Gender Stereotyping exam in my Psychology course and stated the reason that female are attracted to the colour pink is not innate or by genetics but by gender stereotyping.

What some of the people who have submitted answered based on the fact they have never encouraged gender stereotyping with there children to no avail have not realised is that gender stereotyping is not just from learned from parents the but the many media sources that children are subjected to and also friends and family that do conform to gender stereotyping throughout the world.  After all, most people conform to "fit in" with society.

Many years ago there was tribe visited for the first time and it was noted that the female members took no special interest in the colour pink than the male members did and the same with the colour blue, in fact it was found that in some tribes the male members have what we would see as a more "feminine" role in there society, the female members being the hunters and leaders, unfortunately for them they still had give birth first!
