Gynomimicry in the Dwarf Gwembe breed from Zambia

Sexual size dimorphism is a widespread phenomenon in different animal taxa, including the subfamily of goats and sheep. The purpose of this research was to study the sexual dimorphism of males and females of Gwembe Dwarf Goat based solely on cephalic indexes. Eleven indices were calculated for 30 dr...
