Fish x-rays

Hannes and Maria traveled to Boston’s Harvard University to meet with Valentina di Santo from the Lauder Lab at the Museum for Comparative Zoology. Thanks to our collaborators there, we were able to use a 2D-digital X-ray machine to produce x-ray images of the silversides in our QTL mapping study. These images will allow us to count the vertebrae, which increases in wild populations from south to north.
