Question about women's breast size...?

Question

Ok, I have a friend who says that her size is 32A and her mom's is about the same, but her younger sister looks like she has a DD.. Also, I've been surfing through many questions up here and seen many girls complaining why their breasts arent as big as their sisters or their mothers, many of them saying that their sister's size is small and their size is big.. Different stuff based all around one mislead theory: Breast sizes come from genetics.. I have come to believe this thing is not true after all the different cases I have seen up here.. So can someone please enlighten me what really causes natural breast growth? Is it diet, milk and fat or is it genetics?, I don't think genetics play a major role at all.. And aslo, we all know about Jessica Simpson having big breasts and Ashlee Simpson having comparitively small ones.. I think it is more about diet, and having fat food or drinking milk and stuff more.. P.S, I'm just puzzled and curious. So can you please tell me if what I think is true, and if not, please tell me what is the science behind it.. If its genetics please explain

NOTE:
I would like to request you not to post lousy answers like "guys like smaller boobs", "you're lucky to have small boobs", "implants" or "be happy with what you have" or that kind of stuff.. Please give me a reasonable and logical answer because I am really confused

I do think it is genetics, but some people tend towards one family member's genes than the other. Just like how sometimes you can have two sisters from the same mother and father, and sometimes they look exactly the same, while sometime you have two completely different looking people. My mom has a smaller set than I do, but I don't have to look any farther than my dad's side of the family to find out why I have a larger set (all the women on his side of the family have huge breasts). Heck, even two parents that look exactly the same can have a child that looks completely different from them if both parents manage to have the same recessive gene, and that resessive gene somehow manages to come to the fore. Diet can effect it as well, but genetics even plays a hand in that, because genetics  can determine where the fat will be stored. A lot of it is stored in my chest, but other area's have less, such as my posterior.

I hope that answers your question.

You have to remember that you can't just get your boobs from your mom. Just because your dad is male that doesn't mean he doesn't count. Or, his side of the family at least. 
So I do really think it is mostly genetics.  
Take my sister and I for example. We are the same height, and we grew up in the same house, so we had roughly the same diet available to us, but she overeats and prefers fast food and has been overweight for all her life, and I've been an average size all my life. And yet, she is a 36A and I am a 36D. 
So having a certain diet doesn't really effect how large your breasts get. The only thing that explains our difference in breast size is that my dad's side of the family has really small breasts, and my mom's side of the family has relatively large breasts. 
Some people's breasts grow with their weight, but hers didn't for some reason. But once they start to lose weight they usually lose cup sizes first.
My sister started working out alot and now we are the same weight but her boobs are way smaller than mine still :&#92; She's always like "thanks alot dad!" lol

do you realize that every each of us is different even tough in a family.i have six siblings with four girls.we do not have the same looks like other family and i always ask why my sister looks mature than me.but then when i study science i know that our DNA is different.that is why our looks and shape is different.

Heredity & genetics.
