  • We found three alleles from two separate regions within In(3R)Payne with significant additive effects on wing size after the additional effect of the inversion itself had been taken into account. (genetics.org)
  • The presence of multiple regions within In(3R)Payne controlling size is consistent with the idea that inversions persist in populations because they contain multiple sets of locally adapted alleles, but more work needs to be done to test if they are indeed coadapted. (genetics.org)
  • However, before tests such as these can be carried out, it is first necessary to establish whether or not there are multiple regions within an inversion impacting components of fitness. (genetics.org)
  • 4) Inversions affect recombination rates in the uninverted regions of the chromosome. (genetics.org)
  • cause
  • More recently, K irkpatrick and B arton (2006) have proposed that locally adapted alleles and migration can cause a new inversion to spread to high frequency. (genetics.org)
  • shown
  • If a double-stranded DNA, shown in gray, undergoes duplication and inversion, then the resulting molecule precisely demonstrates the strand parity (both within and between strands). (biomedcentral.com)
