One example of gene conversion among the 7E genes. The x-axis gives position around the 7E gene at 10.15845047. The gene is located from position 0 to 1000. Each of the 87 other 7E genes is assigned an identifying number from 1 to 87 (y-axis). A 30-bp window was moved in 1-bp steps across the sequence around 10.15845047 (x-axis) and the best match of sequence in the window to any other 7E gene region was recorded (y-axis). This plot illustrates a gene conversion event involving 10.15845047. The average percent nucleotide identity between the first portion of 10.15845057 sequence and 13.68960122 is 94%. The average nucleotide identity between the 3′ portion of 10.15845057 and 2.164863366 is 97%. The transition between these regions is abrupt. Where the chromosome-10 sequence matches chromosome 13 best, it is only ∼80% identical to chromosome 2, and where it matches chromosome 2 best, it is ∼91% identical to chromosome 13. Both 10.15845047 and 13.689601222 contain the common TM3 frameshift and premature stop, but 2.164863366 does not.
