Table 1.

Results of wild-type (WT) diploid and autotriploid Hyla chrysoscelis female two-choice tests. Stimuli pairs used to estimate the preference function of WT and autotriploid H. chrysoscelis. Proportion of females responding to alternative 1 (= Alt 1) are listed, along with 95% credible intervals. n, number of females responding; χ2-values (d.f. = 1) for 4 × 4 χ2-tests of the difference of the proportions choosing Alt 1 by ploidy level. LCL, lower confidence limit; UCL, upper confidence limit.
