Your genes code for all your traits. Some genes are dominant and expressed if you receive a copy from one parent. Others are recessive and only apparent if you receive a copy from both parents. Genes ...

Why are some genes dominant? Such as those for brown eyes over blue eyes, or so I am led to believe. Or do they actually blend in some way? Here's what science has to say: In the 19th century, ...

Dive into the difference between dominant and recessive genes. How could you take a piece of information and make it vanish from one generation, and then have it reappear? The only way is if the ...

Populations live in rapidly changing environments – droughts come and go, food sources change, human activities reshape habitats. For scientists, this raises a fundamental puzzle: How do populations ...

As a group, carriers of recessive disorders are slightly less healthy and have a reduced chance of having offspring. This disadvantage is greatest for carriers of a recessive gene for intellectual ...

Rare genetic traits are features that are uncommon within the general population. They can lead to different observable features or to rare physical abilities. Rare genetic traits are typically ...

Autosomal inheritance is when a parent passes down a condition to a child via autosomes, a type of chromosome. In autosomal inheritance, a copy of a faulty gene from one parent can cause a condition ...
