Success of holocentric chromosomes natural competitive experiment on a global evolutionary scale (GA17-21053S)

Holocentric chromosomes, as a structural alternative to monocentric chromosomes of holocentrism which is only possible by comparing holo- to monocentrics. We will analyze species and phylogenetic diversity of the l...
