When I meet someone for the first time, I always notice their eyes. Here are some cool facts about people with green eyes.
Sickle cell disease is painful for sufferers and can sometimes be dangerous. Genome editing may one day correct the mutation that causes the disorder.
Did you know that up to 2% of genes in the human population are actually from Neanderthals? Mood disorders and sleeping patterns are among the traits influenced by these genes. Read on to learn more about the traits modern humans have in common with Neanderthals.
Interested in genealogy? Check out this list of ten facts you may not have known about your DNA and biological connections to ancestors!
Genetic diversity is the variation in the characteristics inherited from the parent organisms in a population of a specific species. Genetic diversity can come about through a number of ways: mutations, sexual reproduction, migration, and population size.
It was not so long ago that there was a widespread belief that babies were born blind and only gradually become able to see.
The discovery of a single tooth led to the belief in an ape-like creature had once roamed the plains of the New World.
We know that everyone's DNA is unique, but do you know exactly how forensic scientists tell people apart from their DNA? In this article, we explore the concept of microsatellites (or STRs) and apply this knowledge to tackle an exciting mock case example with riveting twists and turns.
A genealogy timeline can help you organise your family history and open up new lines of enquiry. Learn how to create a genealogy timeline to uncover more of your family history.
They live in a rainbow world the rest of us can never see. Thanks to an eye mutation, an incredibly small percentage of women view their day with supervision, seeing colour where the rest of us see normal shades or even monochrome.
Hair color is primarily genetic, and red hair is caused by mutations in the MC1R gene. The gene for red hair also causes an increased sensitivity to sunlight and a reduced sensitivity to anesthesia. Contrary to internet rumors, redheads are not going extinct! Famous redheads include Queen Elizabeth I and Malcolm X.
If you have red hair or blue eyes, then you're a mutant. There's nothing you can do about it except read this page to find out why nature selected you for mutantdom.
Despite contrary advice, marrying a first cousin can indeed result in a greater probability of birthing a child with genetic defects. The Amish avoid these close marriages, too.
Several external factors affect the way we perceive eye color. This article discusses how environmental factors can impact hazel eyes, making it easy to mistake them for green eyes.
Prior to the discovery of blood groups, blood transfusions were often deadly. Physicians attempted the use of milk and animal blood as an alternative to human blood, but met with limited success: the discovery of blood types allowed modern transfusions to safely take place. Blood typing, blood groups around the world, and the genetics of blood types are discussed in this article.
Telomeres protect the ends of chromosomes. Telomerase is an enzyme that stops telomeres from shortening. Both may play a role in the aging process and in cancer development.
Gene drive seeks to insert or remove a chosen trait in the genome of an entire species. Future applications include eliminating malaria, the zika virus and other diseases.
My DNA results from 23andMe included 800 years of family history, future health risks, and a better understanding of my relationship with my sister. You might discover unknown things too.
The Y chromosome contains haplogroups which allow people to trace their family history, genes which control male development, and may actually be disappearing.
Dinosaurs Alive is an exhibition consisting of large, animatronic dinosaurs. This article contains photos of some of the models and facts about the real animals.
