Royal portraits confirm "Habsburg jaw" was caused by inbreeding
WebInbreeding leads to low heterzygosity. A common crop breeding strategy is to have two inbred lines (homozygous at most loci) and then cross them to make a hybrid that is heterozygous at many loci and which has hybrid vigour (the payoff from having very high levels of heterozygosity).
