| This is because a single locus does not define the polygenic trait, but rather it is the net effect over multiple loci, which defines the trait. |
| At the present time, there is no terminology or method to distinguish simple polygenic traits from complex polygenic traits. |
| Quantitative genetics is the study of the principles underlying the inheritance of polygenic traits, and a few generalizations can be made. |
| In contrast, acoustical communication has been suggested to have a polygenic mode of inheritance. |
| Studying polygenic traits is difficult, since with each added set of alleles, the number of possible genotypes increases geometrically. |
| However, there has been no convincing success in describing the polygenic background of common obesity. |
