chemistry Posted December 4, 2003 Posted December 4, 2003 Height is proportionate to the growth of skeletal bones which occurs through ossification of cartilage; secondary sites of ossification fuse with the central site of ossification when growth ends. I have not looked into the area of height genetics. All I know is that height is polygenic. Nevertheless to what extent is one's full height applicable to recessive and dominant factors? I am wondering if this even applies. Virtually all of the men I have seen are taller than their fathers or at least as tall as their fathers. I suppose that most of the excessive tallness is attributed to the role of androgens in facilitating growth of skeletal bones. Nevertheless there are a couple of individuals who are actually shorter than their fathers despite exercise, which suggests that recessiveness may be applicable. Nevertheless observations suggest that this is very rare. Especially when you look at asian populations, the sons are so much taller than the fathers. It seems to me that height is largely attributable to environmental factors...how much you exercise, eat, how much calcium you ingest during growth.
YT2095 Posted December 4, 2003 Posted December 4, 2003 I`de go along with the last part also. the standard of nutrition has been on the increase significantly esp in developing countries, and produce not native to certain areas are brought in (Imported) on a regular basis now, Global economy and the rellative inexpensiveness of transportation has brought about many dietary changes, and yes, even here to good old England we have in most supper markets, foods that were`nt even know about in to 50`s and some up until the 70`s (although they did cost alot! even then). I`de think that would play a significant role, especialy since it seems to be a more recent phenomenon, and we certainly can rule out Gravity diminishing or evolution
