When I was a kid I truly used to believe that all cows that were brown were female and the black and white ones were male (bulls). I thought it was great that they and others so easily could see which was which. But I didn't really know what to think about the brown and white ones....
It took a few years before I understood that the colors had nothing to do with their gender.
