Why do you think this? Because some of the most renown chefs are men? There are plenty of well-known female chefs too. I don't think cooking is a gender-based skilled. Just up until a few decades ago, "a woman's place was in the kitchen" and a man's place was not, so women were better cooks than men in general (maybe not in restaurants).
Ahh that explains it. What a hit and miss method of selecting a roommate! Of course, I've lived with friends before and we were less friendly by the end of it because they were such slobs or had such peculiar habits. I almost went the CL route but I really am happier living by myself.
Not for my part. I just expect a roommate to do the basics like cleaning the dishes they use, taking out the trash on occasion, picking up their dogs' shit in the backyard (without having to be told to), and maybe vacuuming once in a while. I don't expect a housewife, just a decent roommate.
