Large number of genes that contribute to human height like leg length and torso length also environmental factors come into play. Complex genetic traits: a lot of genes associated, a lot of alleles (more than 2) and environmental. Tobacco plants in f2 is intermediate but also some tall and some dwarf. Human eye color effected by 15 different genes. Regression to mean- the most common phenotypic class we see tends to be the average across the population. Too many genes that affect eye color to use the method to determine the number of polygenes for the trait. As your genetic liability goes up, aka as the genetics you have contribute toward phenotype, you have more and more alleles leading to that issue, reach point where you are considered affected. Environmental effects in the uterus that effect the development of fingerprints.
