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 ...

When we think about genetic inheritance, we usually leap to DNA, the four-letter code containing the instructions for building a living organism. Scientists know that DNA encodes everything from hair ...

For more than a century, heredity has been framed through the tidy logic of Mendel’s pea plants: traits pass from parent to ...

Genetic inheritance may sound straightforward: One gene causes one trait or a specific illness. When doctors use genetics, it’s usually to try to identify a disease-causing gene to help guide ...

A new study suggests that the long-standing Mendelian view of genetics has some blind spots.
