The overall ex situ populations were lower in genetic (allelic) diversity compared to in situ populations.

Inbreeding coefficients were near zero or negative indicating that inbreeding is not common.

Some populations have an excess of heterozygotes (negative FIS).

Three unique genetic clusters occur in the San Marcos River.

Genetic analysis indicates the genetic diversity of the wild population is dynamic both temporally and spatially.
