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 ...

Scientists find hundreds of inherited DNA patterns that defy classic Mendelian genetics
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 ...
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 ...
Parents pass their genes down to their kids, with a child inheriting about 50% of their genome from each parent. But there is another kind of genetic code known as the epigenome that can also be ...
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 ...

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 ...
Scientists use tools like Punnett squares to predict how traits are passed from parents to offspring. Features like freckles and eye color are examples of these traits. Learn how scientists use plant ...
