In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don’t completely follow ...

Researchers at Johns Hopkins University and Texas A&M University have documented at least 522 autosomal sites where DNA methylation patterns pass from parent to offspring without following Mendel’s ...

Many times, scientists embark on a study looking for evidence for a particular hypothesis, and in the process, they come across something totally unexpected and different from their original purpose.

For more than a century, heredity has been framed through the tidy logic of Mendel's pea plants: traits pass from parent to offspring by fixed genetic rules. But a new mouse study suggests that ...
