=== Polygenic characteristics ===
{{Main|Polygene}}

Polygenic characteristics are those affected by multiple genes at different loci.<ref name=":6">{{Cite book |last=Pierce |first=Benjamin A. |title=Genetics: A conceptual approach |publisher=Macmillan Learning |year=2024 |edition=7th}}</ref> These different genes interact in a way to produce a [[Quantitative genetics|quantitative characteristic]], which is a characteristic that presents a wide variety phenotypes, such as height in humans.<ref name=":6" /> The greater the number of genes that interact to influence this characteristic, the greater the number of different phenotypes possible due to more possible genotypes.<ref name=":6" /> Many more characteristics also appear to be affected by more than one gene located on different loci, including diabetes and some autoimmune diseases.<ref name=":7">{{Cite journal |last=Boyle |first=Evan |date=2017 |title=An Expanded View of Complex Traits: From Polygenic to Omnigenic |url=https://doi.org/10.1016/j.cell.2017.05.038 |journal=Cell |volume=169 |issue=7 |pages=1177–1186|doi=10.1016/j.cell.2017.05.038 |pmid=28622505 |pmc=5536862 }}</ref>
