A common example is tongue-rolling — those who can do it are said to have a dominant genetic trait. Except that's all wrong. And so are a lot of other things your teacher called dominant traits, too. » 8/26/13 3:53pm 8/26/13 3:53pm

Carnivorous plant doesn't have time for any of that junk DNA

The other 98% is noncoding DNA, often called junk DNA because there's no clear purpose for it. That name might seem a bit pejorative, but a new study of the bladderwort genome suggests it's oddly… » 5/19/13 1:00pm 5/19/13 1:00pm

Tiny water flea has the biggest genome ever sequenced

The water flea species Daphnia pulex is barely more than a millimeter long, is completely translucent, has no clear divisions between their various body parts...and has the largest genome of any animal we've ever encountered. It has an incredible 31,000 genes in its genome, over 8,000 more than humans have. So what's… » 2/06/11 2:15pm 2/06/11 2:15pm
