Summary:
- This article discusses the concept of "missing heritability" in genetics, which refers to the fact that the genetic variants identified so far can only explain a portion of the heritability of complex traits.
- The author suggests that the missing heritability may be due to the existence of many small genetic effects that are difficult to detect, as well as the potential role of epigenetic factors and gene-environment interactions.
- The article highlights the importance of continuing research to better understand the complex mechanisms underlying the inheritance of complex traits, which could have important implications for fields such as medicine and agriculture.
