Gene Copy-Number Polymorphism Caused by Retrotransposition in Humans
π is shown in 10 kilobase windows for chromosomes containing the DHFR retroCNV (red) and those lacking this retroCNV (black). The location of the retroCNV insertion is marked by an arrow. While there is little difference in nucleotide diversity distal to the retroCNV, there is a recombination hotspot in that region (data from ref. ).
