Combining the outcome out of all crosses we perceived a total of thirty two,511 CO events which were always generate high-resolution CO charts within the D. melanogaster (Figure step one). Considering the increased density regarding markers and also the small number out-of CO incidents for every single chromosome and you will genotyped fly, for each and every CO was backed by of a lot contiguous indicators from the either side and is our presumption that we features seen most of the COs. The total hereditary map length getting D. melanogaster obtained within our crosses is actually 287.step three cM, directly complimentary ancient strategies (282 cM ). A reduced-solution approximation with the shipments of CO rates (c) along chromosome possession predicated on all of our analysis (Profile S2) recovers an equivalent standard, large-size shipping as the early in the day maps based on noticeable indicators –, , –. Affirmed, c try sharply faster close telomeres and you may centromeres, and now we find no CO incidents on the quick 4th (dot) chromosome one to continues in order to meiotic segregation in place of chiasmata .
