There is no inherent connection between(for example)having XX chromosomes and wearing a dress,makeup, and Chanel #5 perfume. Just as there is also no inherent connection between having XY chromosomes and wearing pants,suit and Old Spice aftershave. The latter things are only what our culture thinks are appropriate. We even "gender" all sorts of nonbiological things,like ships being referred to as "she". Sex (biology) and gender (culture) are two mostly separate concepts that are confused way too often, especially in statements like the OP.
