It is determined by polygenetic inheritance (NB I think this should read polygenic inheritance)

Explanation:

Polygenic inheritance occurs when multiple genes act together to produce one trait. A good example of this in humans is height. The trait for height is not simple the result of 2 alleles of 1 gene, but 2 (or more) alleles of several genes that all work together to determine height. These traits are sometimes called complex traits or quantitative traits and do not undergo simple Mendelian inheritance.
