Frog Fertilization
Animal hemisphere Sperm entry point
Establishes the dorsal/ventral axis Ventral side – sperm entry Dorsal side – gray crescent Organized by sperm centriole

Frog Cleavage
Unequal radial holoblastic cleavage Yolk retards division of vegetal pole
Second cleavage starts before first is finished
