Fig. 2From: Birth, expansion, and death of VCY-containing palindromes on the human Y chromosomePalindrome expansion. a–e of Figs. 2, 3, and 4 show results from samples with different structural variants that correspond to sections c–g of Fig. 1. a, b Fiber-FISH image for HG01781 showing an additional copy of the short red and green+pink signals, and genomic interpretation. c Loupe file showing increased read depth in distal P8 and the distal flanking sequence, with a junction at the location of the black arrow. d Breakpoint PCR amplifies a fragment in HG01781, but not in HG03006. e The top and bottom sections show two regions of the reference sequence with a 92-bp repeated sequence indicated in upper case blue, except for differences between the two copies which are in orange and purple, respectively. The middle section shows the breakpoint sequence trace revealing recombination between the two 92-bp repeatsBack to article page
