Exploring the parental origin of potato dihaploid DNA

Amundson et al. investigate the fate of parental DNA in crosses that produce uniparental dihaploids  By Kirk Amundson and Luca Comai  Background: Plants carrying only the chromosomes of one parent, i.e. haploids, are very useful for research and breeding. Certain crosses are known to yield haploid…
