The vegetal pole of a frog zygote differs from the animal pole in that the vegetal pole has a higher concentration of yolk.
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.
- Lower animal hemisphere or lower vegetal pole which is white in color.
Thus, the vegetal pole of a frog zygote differs from the animal pole in that the vegetal pole has a higher concentration of yolk.
