Scientists found that some inherited traits can bypass the traditional rules of genetics, revealing a surprising new layer of ...

A major mouse study found that some inherited traits are passed down through epigenetic changes that break the classic rules of genetics. Researchers discovered hundreds of cases where these chemical ...

Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA ...

James Dewey Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped launch a revolution in biology and medicine, died Thursday at age 97. He died in hospice care after a brief ...

A new international study challenges the century‑old dominance of Mendelian genetics, arguing that most traits arise from complex interactions among many genes rather than single gene–trait links.

The genetic bases of the seven pairs of contrasting traits in the garden pea that were described by the ‘father of genetics’, Gregor Mendel, have long puzzled scientists. The discovery of the genetic ...
