At the beginning, the inverted arrangement lacks variation, while the ancestral one does not. If the inverted haplotype is not lost (eg. due to drift), the variation in the inverted arrangement is increased over time, and recombination rate in the inverted region is somewhat restored as more homozygotes are introd… WebInversion – when a segment of a chromosome is reversed end to end.
