Epigenetics

The video explores the complexity of genetic traits, emphasizing that traits like eye color are polygenic and not as simple as Punnett squares suggest. It introduces epigenetics, explaining how identical twins can have different disease outcomes due to epigenetic factors. The video details how epigenetic marks, such as methylation, influence gene activity and provides examples in rodents, like the GR and agouti genes. It discusses the inheritance of epigenetic marks and their role in development. The importance of epigenetics in understanding diseases like cancer is highlighted, with a focus on epigenetic therapy as a potential treatment avenue.

Discuss the impact of environmental factors on the agouti gene in mice.
