Figure 4From: Evolution of male genitalia: environmental and genetic factors affect genital morphology in two Drosophila sibling species and their hybridsAnalysis of the morphological resemblance of hybrids to their corresponding parental strains. Hybrid mean Euclidean distances (and confidence intervals) to each mean parental shape of each cross. Dk: Drosophila koepferae; Db: Drosophila buzzatii. Cross 3512 (●); Cross 4853 (■); Cross 4855 (◆); Cross 8832 (▲).Back to article page
