Question:
How is height determined in children? Is one parents genes more dominant in determining the height of their children?



Replies:
Actually, if you think about it, there are many, many genes that determine one's final height. There are genes necessary for muscle and bone development, genes that code for hormones necessary for growth such as growth hormone and metabolic enzymes. So you can't really say there is one gene for height. If there were, there would only be 3 phenotypes possible: short, medium and tall. Height is not only polygenic, but multifactorial as well, ie. the environment plays a role. If one's mother smokes during pregnancy or childhood, if one's nutrition is not good, etc. full genetic height may not be possible.
