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

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

Genetics influences who of us are more likely to experience a relationship breakdown, and who are more likely to remain ...

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 ...

Some variation is the result of differences in the surroundings, or what an individual does. This is called environmental variation. Humans, dogs and goldfish are examples of species. Different ...

Most people with ALS don’t have a family history of it. Still, some cases of ALS are linked to inheriting specific gene mutations. Even nonfamilial cases can be linked to sporadic gene mutations that ...

All of the different plants on Earth—from mango trees to marigolds—have come about thanks to the simple rules of genetic inheritance, which determine how traits are passed on from one generation to ...
