Short repetitive sequences in green algal mitochondrial genomes: potential roles in mitochondrial genome evolution.

abstract：:The little fire ant, Wasmannia auropunctata, displays a peculiar breeding system polymorphism. Classical haplo-diploid sexual reproduction between reproductive individuals occurs in some populations, whereas, in others, queens and males reproduce clonally. Workers are produced sexually and are sterile in both clonal a...
