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 ...

Researchers linked orange cat fur to a 5-kilobase DNA deletion near ARHGAP36, which may explain the trait's inheritance and ...
