Embryonic temperature determines adult sexuality in a reptile

摘要: Gonadal differentiation in amniote vertebrates is controlled by one of two mechanisms: genotypic sex determination (GSD) or environmental (ESD)1. After the fetal gonad produces steroid hormones which govern development other components sexuality2,3. Thus, primary determiner thought to operate solely as a trigger that initiates cascade events culminating adult differences. In leopard gecko (Eublephans macularius), gonadal and morphological determined incubation temperature, with relatively 'hot' temperatures (32 °C) resulting mostly male offspring 'cold' (26 only female offspring4,5. We report here reproductive behaviour endocrine physiology an influenced temperature experienced embryo. Also, perception courtship temperature. These data indicate this species, has differential effects on sexuality.
