every family has a history of diabetes, heart disease and cancer.
so if every family has a history of it, then it is not genetic is it? logic demands this is not luck or random, or passed down.
when will people learn that these things are not genetic, and are specific in the personal health and lifestyle of individuals.
Actually, it is partially genetic. Did you just not study genetics in school?
If the father has a dominant and a submissive gene of diabetes, and the mother only has submissive, the child will have a 50% chance of getting diabetes.
Then if that child got the
Dd (one dominant, one submissive) gene set for diabetes, and he has a kid with another person with
Dd, the child will have a 75% chance.
If that kid has
DD and she has a kid with someone with
dd (two submissives), the child with have a 100% chance of getting diabetes, but will be guaranteed to have the genes
Dd. If he then has a kid with someone with
dd genes, there is small chance the kid will have two submissives,
dd, and will not have diabetes.
In short, Punnet squares.
