Holocentric repeat landscapes: From micro-evolutionary patterns to macro-evolutionary associations with karyotype evolution.

ABSTRACT: Repetitive elements can cause large-scale chromosomal rearrangements, for example through ectopic recombination, potentially promoting reproductive isolation and speciation. Species with holocentric chromosomes, that lack a localized centromere, might be more likely to retain chromosomal rearrangements that lead to karyotype changes such as fusions and fissions. This is because chromosome segregation during cell division should be less affected than in organisms with a localized centromere. The relationships between repetitive elements and chromosomal rearrangements and how they may translate to patterns of speciation in holocentric organisms are though poorly understood. Here, we use a reference-free approach based on low-coverage short-read sequencing data to characterize the repeat land
