Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA ...

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 ...

Mendel's famous laws of heredity, established over a century ago, may not be as universal as once thought. A recent study on ...

Many times, scientists embark on a study looking for evidence for a particular hypothesis, and in the process, they come across something totally unexpected and different from their original purpose.

The blueprint of who we are begins with the genes passed down from our parents. While these inherited traits give us our eye color and height, they can also contain instructions that increase our risk ...

Small plastic or metal bits at the end of shoelaces, known as aglets, prevent laces from unraveling and protect them from wear and tear. Similarly, chromosomes are capped by telomeres—specialized ...

​​When both parents carry SCT, each child has a 50% chance of inheriting the trait and a 25% chance of developing the disease. This is why genetic counselling must be recognized as an integral part of ...
