Figure 4From: Potential use of low-copy nuclear genes in DNA barcoding: a comparison with plastid genes in two Hawaiian plant radiationsHaplotype networks for plastid and nuclear genes in Cyrtandra. Haplotype networks for plastid (psbA-trnH) and nuclear (Cyrt2, Cyrt4) genes in Cyrtandra. The small empty circles indicate “ghost” alleles (intermediate alleles that were not recovered in any of the accessions sampled).Back to article page
