From: Conservation genetic evaluation of Juniperus communis sensu lato in Slovakia

Admixture regression of needle length/width ratio in two juniper taxa and their hybrid. The parental forms can be defined by the intervals of 0.0–0.2 (ssp. nana) and 0.8–1.0 (ssp. communis), while the rest corresponds to nothovar. intermedia. The red line represents predicted values of the trait based on a partially linear semiparametric model.
