Yes, the number of placentas (chorionicity) and amnions (amnionicity) depend on the stage at which the fertilized egg splits. The earlier the split, the more likely each fetus will have its own placenta and amnion. If the egg splits before or by day 3 - each fetus will have its own placenta and amnion resulting in a dichorionic diamniotic pregnancy.

What are MZ and DZ Twin Pairs?
MZ twins are identical twins that share 100% of the same DNA. DZ twins share only 50% of their DNA (fraternal twins). MZ twins are always the same gender, whereas DZ twins can be the same gender or one male and one female. DZM would be the male pairing of DZ twins, DZF is the female pairing, and DZO is when there is a male and a female.
What does diamniotic monochromatic twin pregnancy mean?
It means that the twins share the same placenta but different anemic sacs.
How is identical twins created in the mother's womb?
With identical twins, one egg (zygote) from the mother is fertilized by one sperm from the father, and then very early in development the embryo splits and two fetuses grow. Spontaneous division of the zygote into two embryos is not considered to be a hereditary trait, but rather a spontaneous or random event. If the zygote splits very early (in the first 2 days after fertilization) they may develop separate placentas (chorion) and separate sacs (amnion). These are called dichorionic, diamniotic (or 'di/di') twins. While all fraternal twins are 'di/di', this occurs 20 - 30% of the time in identical twins. Most of the time in identical twins the zygote will split after 2 days, resulting in a shared placenta, but two separate sacs. These are called monochorionic, diamniotic ('mono/di') twins.These twins are very similar genetically, and share a single afterbirth. Very occasionally, twins will also share the same sac (fluid cavity). In about 1% of identical twins the splitting occurs late enough to result in both a shared placenta and a shared sac. These are called monochorionic, monoamniotic ('mono/mono') twins.
What does research comparing the rates of schizophrenia in monochorionic twins and dichorionic twins suggest?
Concordance rates that suggested a role of genes in schizophrenia might more accurately be interpreted as a reflection of the influence of shared prenatal experience.
What does dichorionic mean?
Literally, having two chorions and two placentas -- used especially of human fraternal twins. That is to say, not identical twins growing in a single sac, but two completely separate fetuses with separate placentas.

What is the genetic difference between identical and non identical twins?
Identical twins are formed by the separation of the same embryo containing same genetic coding. thus the the twins are identical as formed from the same embryo. But this is not the case in the non-identical twins as they are formed from the individual embro each having different genetic coding.
