Our results show that offspring phenotypes are mainly determined by genetic factors and maternal effects, while paternal effects and residual environmental influences are minimal. This suggests a high evolutionary potential for head shape in the Hungarian meadow viper, which suggests a strong contribution of this ecologically relevant trait in shaping the ability of this endangered species to adapt to changing conditions and/or habitats and which would be useful to consider in captive breeding procedures for conservation efforts.
