The blueprint of who we are begins with the genes passed down from our parents. While these inherited traits give us our eye color and height, they can also contain instructions that increase our risk ...

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

Although schwannomatosis is a genetic condition, the inheritance patterns for this disorder are complex and much less clear than for both NF1 and NF2. Some cases of schwannomatosis are familial, with ...

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 ...

Genetic information in the DNA and modifications, such as DNA methylation, define the epigenetic landscape and phenotype and show both Mendelian and non-Mendelian heredity. Scientists have long known ...

Retinitis pigmentosa (RP) is an eye condition that can be genetic. In this way, people usually need to inherit two copies of a genetic variation that causes RP, one coming from each parent. RP may ...

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 ...
