Table 5 Summary of means, standard deviations (SD), sample numbers (N), mean mid-parental values (MPV) for thirteen morphological traits in C. penicillata x C. geoffroyi hybrids (GP). The “P-values of t-Tests between MPV and Hybrid Means” column shows p-values from t-tests between GP hybrids and the MPV. The “P-values of t-Tests between Parental and Hybrid Means:GP-G” column represents p-values of Welch’s t-tests between C. geoffroyi and GP hybrids. The “P-values of t-Tests between Parental and Hybrid Means:GP-P” column represents p-values from Welch’s t-tests C. geoffroyi and GP hybrids. Significant p-values are indicated as “*” for p-value<0.05, “**” for p-value<0.01, and “***” p-value<0.001. “Cm” refers to centimeters, “mm” to millimeters, and “g” to grams
