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 ...

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 ...

An analysis of genetic data from over 900,000 people shows that certain stretches of DNA, made up of short sequences repeated ...

Forty years ago, a postdoctoral researcher named James McGrath who would go on to spend more than three decades as a clinical geneticist and research scientist at Yale, made a discovery that advanced ...

A multi-omics study identifies causal genes and biological subtypes of long COVID, revealing new therapeutic targets for ...

For millennia, evolution has intrigued many great thinkers, prompting questions about how new traits emerge as species adapt over time. Then, attention shifted to natural selection and the inheritance ...

Epigenetics is the study of various heritable alterations that control gene expression without changing the DNA sequence. 1 The name epigenetics comes from the Greek prefix “epi”, which means on top ...

Hair genetics can come from either parent, and multiple genes can determine hair traits, such as color, texture, and growth. Genes can also affect hair loss. Although it can run in families, this is ...
