Multifactorial diseases, such as coronary artery disease, can be as complex as their name suggests. How much can we hope to understand about diseases with such variation in inheritance? Aa Aa Aa ...

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 ...

In 2015, biologists developed a breakthrough technology known as "active genetics," which results in parents transmitting a genetic trait to most of their offspring (instead of 50 percent receiving ...

The COVID-19 pandemic gave us tremendous perspective on how wildly symptoms and outcomes can vary between patients experiencing the same infection. How can two people infected by the same pathogen ...

For decades, high school teachers used Gregor Mendel and his pea plants to teach kids in ninth grade on up the fundamentals of genetics. Today’s kids don’t care beans about those peas. They want to ...

Research on Tourette’s indicates that the condition is strongly influenced by inherited genetic factors, with environmental factors also contributing to its development. Tourette syndrome is a ...

Next-generation sequencing (NGS) technologies are now routinely used for gene identification in Mendelian disorders. Setting up cost-efficient NGS projects and managing the large amount of variants ...
