cooking gene?

I made chapati's today. There is no better cure for homesickness than making your all time favorite meal growing up. Many people complain that it is a tedious task but for some reason, I think it's a pretty snappy job, once I figured out how to make the perfect dough that is.
Today I had my superhelper aka lil man. He loves to help with the cooking and I love to have him help me-only that the clean-up takes as much time as it does to cook!! Today was no exception and I figured out you are only a kid once so I let him play with the wheat flour, corn flour, pour water here, stir, blow, and touch everything he shouldn't be. So by the end of it, the two of us and everything around us was looking 'heavenly'.
I was explaining to lil man how it's nice that he gets to help me roll the chapatis because he can learn how to cook-letting him know that my brother is a great cook.
Of course he had a smart reply, " I'm already a good cooker", LOL, ok corrected the 'cooker' part then asked him why he thinks he is already good. He proceeded to explain that he is already good because he inherited 'cooking' from my brother, just like he inherited his drawing skills from grandpa.
Ok, my bad, maybe I didn't explain the whole passing down genes very well but I can see he picked up something. I'm just not sure my brother's culinary skills bothered to criss cross all the way down the lineage to my son but only time will tell.

PS. The Chapatis were great even with all the over-rolling and prodding of dough that lil man does, so he may be onto something here.
