Scientists discover inherited traits that break Mendel’s Laws of genetics
A study in mice has revealed that some epigenetic traits are inherited in ways that defy Mendel's classic laws of genetics. These non-Mendelian patterns may allow organisms to adapt to environmental pressures more rapidly than genomic mutations.
Why it matters
This discovery challenges foundational biological principles and suggests that epigenetic inheritance plays a more significant role in evolution than previously understood.
For more than a century, biology has been guided by the principles of inheritance first described by Gregor Mendel through his famous pea plant experiments. While those rules explain how many genetic traits are passed from parents to offspring, scientists have also known that DNA sequences are not the whole story.
The report summarizes scientific findings from a peer-reviewed journal without political or social bias.
