comment Is ovum + ovum fertilization possible for human?
With identical twins, the cells are diploid and start as one cell, but another breaks away and forms a seperate zygote. In fraternal twins two separate ovums are fertilized separately. Once you have conception (sperm fertilizing eggs) you have a diploid cell. With the exception of some know genetic disorders (downs syndrome) all humans are diploid, so two diploid cells don't join themselves and start dividing in utero.
