Abstract:

Electrophoretic analysis of allozyme polymorphism in six populations of the conchostracan Eulimnadia texana indicates substantial levels of genetic variation within populations and significant differentiation between them. The distribution of genotypes within populations further indicates a general pattern of non-random mating that is consistent with the capability of females to reproduce by selfing hermaphroditism. The magnitude of this inbreeding by selfing varies greatly among populations, but is highly correlated with the frequency of males. In the typical state of a strongly female-biased sex ratio, a population of E. texana has a mixed mating system in which both selfing hermaphroditism and sexual outcrossing are of substantial magnitude.
