The comparison of the overall size of homologous transposon. Insertion sites in B. tryoni /B. neohumeralis (A) and B. tryoni /B. jarvisi (B). For each species pair comparison, homologous DNA segment size varies more in the vicinity of transposon (mariner) sequences (red points) than at random sites (black points). The control group consisted of an equivalent number of sequence fragments drawn at random from the two relevant assemblies.
