The article discusses how variations in the genetic material of cells can impact breeding and genetic theories. It explains that genetic information in cells can change due to factors like stress and environmental influences. These changes can affect the traits passed down to offspring. The research suggests that traditional genetic theories need to be updated to include these new findings. The study classifies genetic variations into three categories: Mendelian genetic variation, somagenetic variation, and epigenetic variation. This new understanding can help improve genetic analysis and breeding techniques.
