We and additionally observe a negative dating between total ? and ? [R = ?0
c and ? according to one hundred-kb adjoining screen which have screen labeled into the 6 types of equal amount centered on c [CO1, Co2, . CO6 demonstrating expanding rates away from c] The average c (cM/Mb/women meiosis) thinking to the half dozen groups is: 0.078 (CO1), 0.727 (CO2), 1.439 (CO3), 2.294 (CO4), 3.299 (CO5) and you will 5.964 (CO6). Bluish columns show results whenever entire chromosomes was assessed. Orange columns show results immediately after deleting centromeric and you can telomeric places that have noticeably less CO prices. 1246 (P = step one.6?10 ?5 ) getting entire chromosomes and Roentgen = ?0.1191 (P = step 1.2?10 ?cuatro ) immediately after removing telomeric/centromeric countries.
Several hypotheses could be used forward to explain the various other terrain to own CO and GC along the D. melanogaster genome. Divergent DSB repair pathways was indeed recommended inside the Drosophila like in fungus , , that have an excellent synthesis-built strand annealing (SDSA) pathway which is associated just with GC occurrences, just like the resolution of your own double Holliday junction (DHJ) is also generate sometimes CO otherwise GC (Contour S1). New recognition out of GC incidents on the fourth chromosome firmly ways the experience out of SDSA, no less than getting an excellent chromosome totally devoid of CO, and you can demonstrates SDSA tends to be acting across the whole genome. The latest observation you to ? Читать далее →
