Sickle cell disease is painful for sufferers and can sometimes be dangerous. Genome editing may one day correct the mutation that causes the disorder.
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.
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.
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.
Dinosaurs Alive is an exhibit consisting of large, animatronic animals. This article contains photos of some of the models and facts about the real animals.
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.
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.

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.
The discovery of a single tooth led to the belief in an ape-like creature had once roamed the plains of the New World.
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.
It was not so long ago that there was a widespread belief that babies were born blind and only gradually become able to see.
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.
The Y chromosome contains haplogroups which allow people to trace their family history, genes which control male development, and may actually be disappearing.
My DNA results from 23andMe included family history going back 800 years as well as future health risks. It even gave me a better understanding of my relationship with my sister.
When I meet someone for the first time, I always notice their eyes. Here are some cool facts about people with green eyes.
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.
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.
