Gateways to Hawai‘i: Genetic Population Structure of the Tropical Sea Cucumber Holothuria atra

Figure 2

Haplotype network for Holothuria atra. Each circle represents a unique haplotype connected by a line to those that differ by one base pair. Nodes on lines indicate a missing haplotype, and numbers represent multiple missing haplotypes. Each haplotype is color coded by site, and circle size is proportional to frequency. The smallest circles represent one occurrence of a halotype.
