How to find contribution each gene makes to phenotype

Many important agricultural traits such as crop yield, weight gain in animals, fat content of meat are quantitative traits, and much of the pioneering research into the modes of inheritance of these traits was performed by agricultural geneticists. Many human phenotypes such as IQ, learning ability and blood pressure also are quantitative traits. These traits are controlled by multiple genes, each segregating according to Mendel’s laws. These traits can also be affected by the environment to varying degrees. The following are examples of quantitative traits that we are concerned with in our daily life.
