The correct answer to the question: Mary and Juan are twins who developed from two separate fertilized ova that were fertilized by two different sperm. What type of of twins are they?, would be: Dizygotic twins.

Explanation:

Dizygotic is literally the term used for what we normally call fraternal, or non-identical twins, and it describes the case of babies that are conceived at the same time, but from two separate ova from the mother, and two different sperm from the father. It is a situation that is very common in certain regions of the world, but it is uncommon in others. However it may be, usually women will ovulate only one ova from one side of their ovaries, per cycle. Still, there are women, given certain circumstances, who will ovulate two, and sometimes more, ova in one single cycle, either from one, or both ovaries, and these can be fertilized by the sperm of the father. When this happens, as is the case of Mary and Juan, although they share the womb, genetically they are completely different. These are known as dizygotic, or fraternal, twins.
