This paper reviewed the progress of studies on growth of sexual dimorphism in vertebrate.The reasons of growth sexual dimorphism in vertebrate including feeding and digesting,energy allocation between growth and reproduction,species heredity,genotype and phenotype,steroid level,genes expressions of growth axis are analyzed.
在动物世界中,许多种类的雌、雄个体在形态及生长方面存在一定的差异,即两性异形(sexual size dimorphism,SSD)和两性(雌雄)生长差异(growth sexual dimorphism,GSD)。两性异形即同一物种一种性别的个体比另一种性别的个体大;两性(雌雄)生长差异即同一物种一种性别的个体比另一
