Thank you very much Tanay Ji for taking care of my curiosity. As i was reading this very interesting lethal homozygous condition of * Tradescantia* i was wondering why this plant drew so much attention of scientists so that they went to explore even its genetics! More so because i find that it has no economic uses other than its looks as have been described in - http://www.worldfieldguide.com/species-detail.php?taxno=2859&gr=world
However, thank you once again for spending some time for me.
