Based on those sizes and the probability that new mutations that arise are harmful, they computed the load of genetic mutations for each population, and found that Neanderthals most likely had a greater prevalence of slightly disadvantageous genes. Over time, this would have decreased the amount of Neanderthal DNA around modern human genes.

The 'Dark chocolate sneeze' which affects about 25 to 30 percent of the population is on Chromosome 11. Fitting a mathematical model of natural selection onto it, they found that a pattern of weak natural selection because of population size differences between Neanderthals and humans could account for the distance between Neanderthal DNA and genes in the human genome today.
