Transposable elements

Transposable elements (TEs) have the ability to self-replicate and move to new locations in the genome of their hosts. Host genomes have evolved mechanisms to silence TEs, which may break down in species hybrids.

Hybrid dysgenesis in Drosophila can result in gonadal atrophy (male in the middle with atrophied testis). 

We are studying expression of TEs in pure species and F1 hybrids, to identify if TEs are mis-regulated in species hybrids.
