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 ...

For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its ...

A new international study challenges the century‑old dominance of Mendelian genetics, arguing that most traits arise from complex interactions among many genes rather than single gene–trait links.

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 ...

Despite rapid advances in genetic testing in recent decades, more than half of people worldwide with suspected Mendelian genetic disorders do not have an accurate molecular diagnosis. Others endure ...

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 ...
