Answer:
D. Two eggs are fertilized by two sperm.
Explanation:
Fraternal twins are dizygotic or multiviteline, that is, they are formed from two eggs and fertilized by two sperm.
In this case two oocytes are produced and both are fertilized, thus forming two embryos. They are almost always formed in different placentas and do not divide the amniotic sac.
Fraternal twins are not very similar to each other, may or may not have the same blood factor, and may or may not be of the same sex.
They are also popularly known as different twins. In fact they are two ordinary (not identical) brothers who had a coincident gestation.
Answer:
Geographical isolation.
Explanation:
Due to Geographical isolation, there are unique species present in each pond because they can't inter-breed with one another due to no way of movement to one another location. These unique fish species are geographical isolated from one another which is also responsible for its uniqueness. If they are not Geographical isolated so these fishes mate with each other and their uniqueness will disappear so we can conclude that geographical isolation is responsible for the uniqueness of fish species in each pond.
