If you have increasing weight, most on the gut, get checked out by your pcp. ...Read more
Could preimplantation genetic diagnosis or genetic engineering get rid of diseases like Marfan syndrome?
Obedience : This is an interesting question. It's confused by statements, like: "Something that is hereditary “can” be transmitted genetically from one generation to another." What might be more important to discuss is whether obedience can be taught, and learned, or if it might be something neither taught nor learned in the family setting. Non-obedient parents may model non-obedience for thier children. ...Read more
From a medical standpoint, "genetic" refers to the potential heritability of various medical conditions. While some conditions are inevitable (at some point in one's life) as a consequence of simple genetic heritability (eg huntington's disease), a large number of medical conditions (including all behaviorial health disorders) are the expressed final pathway of a ...Read more
