Female swordtail fish prefer symmetrical sexual signal
Article Abstract:
The hypothesis that the swordtail fish, Xiphophorus cortezi, females prefer symmetrical sexual signals was tested by determining whether females switched their preference between two males with or without a symmetrical number of bars. The bars were manipulated in such a way that other male traits were controlled. Observations revealed that females switched their preference between a pair of males when switching which male was symmetrical for bar number. This result suggests that females prefer a symmetrical bar number.

A negative correlation between trait and mate preference in Xiphophorus pygmaeus
Article Abstract:
Direct selection or drift plays the major role in the evolution of female mating preferences among different populations of Xiphophorus pygmaeus. A series of three studies spanning over five years indicate that female preference for large male body size vary between populations. The analysis of the distribution and subsequent spread of large X. pygmaeus shows that female preference for large male body size is negatively correlated with male traits of large size.
