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 ...

Lamia Wahba is studying how information outside the genetic code can pass between generations and what that means for evolution and disease. When we think about genetic inheritance, we usually leap to ...

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 ...

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 ...
