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 ...

Gene editing is now reaching the mainstream, ushering in a new era of genetic manipulation. Traditionally, inserting or deleting entire genes, regulating their expression, and altering specific ...

Your body is basically a walking library of 37 trillion cells, and inside each one is a complete copy of your genetic instruction manual. Think about that for a second. That’s like having the entire ...

Genetic inheritance may sound straightforward: One gene causes one trait or a specific illness. When doctors use genetics, it’s usually to try to identify a disease-causing gene to help guide ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

Hereditary cancer is caused by germline mutations, typically following an inheritance pattern within a family. In contrast, sporadic cancer is caused by somatic mutations interacting with ...
