After the fertilisation of the egg by the sperm in a frog, three regions are formed in the zygote. These are:
- Upper animal hemisphere or upper animal pole which shows pigmentation.
- The grey crescent which is a small area with almost no pigmentation. It is present in between the upper animal pole and the lower vegetal pole.
