John I just wanted to add that you should not be concerned with your height. You are luckier than you realize. There is a LOT of evidence that short men live healthier, happier lives than there taller counterparts. Besides, chicks dig short guys (honest!) Females feel much less intimidated by males of shorter stature and therefore are much more likely to approach them and get to better know them. This may be a evolutionary process(?) Anyway, shorter men will generally have more female friends than there taller counterparts and therefore have a wider selection of possible mates. You should look at being short as a good thing Isn't the understanding of genetics and evolution awesome?

Height is determinded by Multifactorial Polygenic Traits. Polygenic traits are determined by more than one gene, with each gene providing a small, but additive effect. Multifactorial traits are determined by interactions between a gene or genes and the environment, and do not exhibit Mendelian ratios. Polygenic Traits Are Continuously Varying. Polygenic traits usually produce a continuum of phenotypes. Individual genes of a polygenic trait follow Mendel's laws, but together do not produce Mendelian ratios. Understood?

What do you call a gene that is inherited in a dominant fashion but by only 50% of the F1's. 50% of the F1's will express the dominant trait and 50% will be of wild type. The 50% that are of wild type do not carry the gene and have proved to NOT be heterozygous for this gene. I can't call it a true dominant...so, what do I call this gene? NOTE: When this dominant phenotype is bred to another dominant phenotype all offspring express the dominant gene phenotype. When the dominant gene phenotype is bred to wild type 50% express the gene and 50% are wild type and are NOT hets for this gene. I have never ran into this type of gene and don't know what it is called.
