For the same reason that blond haired people dont' always have blond kids, that dark-skinned people can give birth to light-skinned people, and that I have blue eyes while both of my parents have brown/hazel eyes. Excellent point, and one to build on. With every genetic pool of random selection there still exists a calculated percentage of result, one, with a big enough pool of data, that always generates the expected result. Your examples site the effect of dominant versus recessive gene. Much to beth's chagrin, since red hair is carried on a recessive gene, it's calculated that in the foreseeable future the only red heads will come from a bottle. On a more serious note diseases such as hemophilia are statistically calculated and proven at a specific rate, when present in the genes of un-symptomatic parents. Yet, no study on obesity or alcoholism ever produced the same definitive statistical data. Even assuming that alcoholism is carried as a recessive trait, two alcoholic parents should produce a high if not 100% occurrence of alcoholic children. There is no observable evidence of this. Interestingly enough there is a greater correlation of obese children born to obese parents. Does this suggest that obesity is more of a dominant gene trait? I dont' think so. More likely everyone in the family is eating wrong. Being fat and having limited physical activity is "normal" and accepted in the the family unit.
