Modern Europeans on average have about 3% Neanderthal ancestry. However, this ancestry is not distributed evenly across our genomes. This indicates that selection is working on Neanderthal DNA differently than on modern European DNA. In this work we seek to understand the distribution of selection effects in the Neanderthal DNA in current modern humans. Additionally we are interested in how gene expression is affected by Neanderthal DNA.
