Since this is my first post I send my "hi" to everyone . I have few questions to topic mentioned in title: 1.Is there one gene responsible for breast size and shape, another for legs and thighs... or the overall silhouette depands on one gene? 2a.And in case of breast (or silhouette) - which shapes(and sizes) are recesive and dominant? 2b.What are the combination of allels? 3.How big influence on inheriting these traits have father's chromosomes (X,Y)? I've heard from my friends that most of them inherited breast size (I mean they are similar in shape) after mother or grandmother (from mother line; mine is quite similar to my mother). My mother currently has an E(DD) cup but before I was born she had C cup. My aunt (and her sister) however is B cup although she was pregnant already (A was before). I want to know what chance i have of "inheriting" breasts after my mother. I would be very grateful if the answer was from someone who has professional wisdom (someone who is working or teaching in genetics) or know some sites, books, etc. which can give me informations about it.
