WebDoubled haploids(DHs) are plants derived from a single pollen grain and doubled artificially to form homozygous diploids. A DH individual has two identical homologs, so that the amount of recombination information is equivalent to a backcross. The advantage of using a DH population in molecular mapping is that all individuals are homozygous.
