Hi Surajit Da. Yes, Rhoeo discolor has two genomes indicated by α & β. During the meiotic segregation chromosomes comprising of each genomes moves towards the opposite poles. So that, each gamete has either α or β genome, hence the heterozygous condition (αβ) is maintained in the filial generation. It is believed that homozygous condition (αα or ββ) in Rhoeo leads to lethal mutation. Crossing over and synapsis do happen in the chromosomes but only at the terminal region of the arms along a restricted part. But, the sequential and detailed stages are not quite well understood. Regards Tanay
