Solved: the genetics of colour polymorphism in wall lizards

Posted by on Mar 1, 2019 | 0 comments

A new paper in PNAS reveals that the orange and yellow ventral colour morphs in wall lizards is caused by regulatory changes in pterin and carotenoid genes. Interestingly, it seems like the alleles are old and occasionally shared between species. Miguel Carneiro and his team at CIBIO and Leif Andersson at Uppsala led the work, and we helped with the genome, samples, and other bits and pieces. The chromosome-scale genome assembly is of high quality and should become a useful resource – so just get in touch if you want to know if the wallies are right for you too!
