<span>Quail embryos at day 3 of development (similar to human week 5). Left is a normal control embryo that has a straight trunk and the head curves nicely to the right. Middle is an embryo treated with alcohol at an earlier time point (day 1, similar to human week 3). This is mimicking fetal alcohol syndrome in human. Right is an embryo in which the cardiac neural crest cells were ablated. This is mimicking DiGeorge Syndrome. Both abnormal embryos show twist and/or rotation of the body. (Work also has contribution from Lindsy Peterson, a former </span><span>lab member. Adviser: Andrew Rollins) I attached an image with two copies of the same sets of images, the bottom ones have labels on them pointing out some structures of the embryo as part of my description to orient the observer during the judging process. The top part is my participating image.</span>
