how come people get bigger then each other? is it the diet of their particular breed? can you take a smaller breed, isolate them, feed them more and make them a bigger breed or is it all just family genetics? how come say like Polynesians are bigger then regular asain people, I see some Tongans and Samoans that look similiar to me, but a lot bigger?

The growth of the body is usually controlled by the Growth hormone in the body. Since the growth hormone is controlled by gene expression. Altering the genes at the genetic level or injection of growth hormone-alike-protein should help in making one bigger.

It is a bit more complex than the answers you have received. In most societies the taller males mate with the taller females. You have run the genes for height to fixity, variant by population and environment. Samoans are on the " large " end genetically, but can be increased by diet. The genotype expresses into the phenotype. Take any plant and plant it in fertile soil, with lots of water and watch it grow. And visa- versa. Take the Japanese and the Chinese. A different diet and they are taller, on average. You could probably put the variant genetic potential heights, sans food, under a normal curve. The curve might be very peaked, but diet is a variable that really varies. Nature via nurture.

It's totally inherited, all in the genes. You can feed a Pygmy all you want and they won't get any taller, you can put a Samoan on a diet and his frame will still be very large!

Scientifically speaking, yes it IS possible, but if it has been done its been kept a secret, and it isn't very likely at this point as we are only at the beginning of understanding how to do something like that. Easier to just have a tall daddy and do it "the old fashioned way".

anything is possible through genetics. so yeah you can do that, and much much more.

good luck with that. they are not "genetically altered".
