Review on the ecology and evolutionary dynamics of meiotic drive

This summer, over 20 biologists studying meiotic drive in a variety of taxa (including flies, plants, mice, birds and fungi) gathered in the Swiss Alps for a workshop to discuss the outstanding questions on meiotic drive. We were thrilled to be a part of this group. One product of this workshop was a review on the ecology and evolutionary dynamics of drive. You can read the review here:

Mysteries of the genome 11/24/15

Less than 2% of the DNA in human coffeecupgenomes contains conventional genes that code for proteins. Scientists have known for decades that non-protein-coding regions in the genome can have important functions in regulating genes. However, much of the remaining non-coding and non-regulatory DNA consists of sequences frequently referred to as “junk”. This category includes repeated sequences that we know little about but have links to cancer and other diseases. These repetitive genomic regions can go awry causing catastrophic genomic rearrangements and some can even behave like viruses. In this science cafe, we’ll explore the mysterious parts of genomes rich in so-called “junk” DNA. We’ll discuss the controversy over what is considered a “functional genetic element” and how studying genomic differences within and between species helps shed light on a sequence’s functional significance.
