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.
Fraternal twins can happen when two different eggs join two different sperms. Each baby then has its own cord and placenta. These twins may be of the same or opposite sex.
Identical twins are produced when an egg and a sperm join together but then divide into two once they have joined. These twins may share a single placenta and very occasionally may also share the same amniotic sac. Dichorionic Diamniotic is the term for fraternal twins with two placentas and two amniotic sacs. Monochorionic Diamniotic is the term for identical twins with one placenta and two amniotic sacs. The fertilised egg splits between 4 and 8 days. Monochorionic Monoamniotic is the term for twins sharing one placenta and one amniotic sac. The egg splits between 8 and 12 days.
Assuming you're referring to twins, identical twins come from the same fertilized cell that broke into two clumps of cells early in its development and so have identical DNA. Fraternal (non-identical) twins come from from two different cells that were fertilized by two separate sperm and while they develop at the same time, they each have unique DNA.
Identical twins are formed from the same fertilized zygote ( which undergoes division in some later period of pregnancy) while non identical twins are formed from two different zygotes
With identical twins, a fertilized egg splits in two.
With non-identical twins, more than one egg is fertilized.
Identicals are exactly the same non identicals are just regular twins that are not nessecarily similar.
identical twins came from the same fertilized egg that split while fraternal twins came from 2 different fertilized eggs.
identical twins have the same genes from the same parents. Non identical twins have different genes.
identical twins may look the same but their personalty's differ even if it is small,
and no two fingerprints are alike.
Dizygotic twins develop from two separate ova fertilized by different sperm at roughly the same time, they are also called fraternal twins. Monozygotic twins develop from one zygote that splits apart producing genetically identical zygotes; also called identical twins.
They are as similar as any other two siblings.
Assuming their are no mutations the twins wold both have 46 chromosomes. Twins, have the normal number of chromosomes, the only difference between an set of identical twins and two average individual is that twins have identical DNA.
identical twins.
fraternal twins have two different chromosomes
100%Identical twins develop from the same egg, so have the same DNA. The only thing different between identical twins is finger prints, and retinal patterns.
how does the genetic makeup of a fraternal and identical differ
Identical twins would have the most genetic similarities, since they share the same original 46 chromosomes.
The difference between Identical and Non-Identical twins is that Identical twins share the same placenta and are basically identical to one another. Non-Identical twins do not share the same placenta in the womb and two eggs fertilized at time of conception as opposed to one egg splitting in the case of Identical twins. I think that covers the basics. Hope this has clarified things for you.
If two (or more) eggs are fertilised and develop together you will get fraternal twins. Identical twins are the result of a single fertilised egg dividing into two embryos.
Generally, each person has his or her own genetic makeup. Identical twins can have a very similar DNA>
Dizygotic twins develop from two separate ova fertilized by different sperm at roughly the same time, they are also called fraternal twins. Monozygotic twins develop from one zygote that splits apart producing genetically identical zygotes; also called identical twins.
By convention, a clone is an engineered offspring derived from the genetic material of a single adult. Identical twins are genetic copies of each other, but they were formed by the splitting of a fertilized zygote rather than by extracting the genetic material of a single adult.
They are as similar as any other two siblings.
Identical twins come from the same fertilized egg; fraternal twins come from 2 fertilized eggs.
The DNA of identical twins and of clones is, apart from random, environmentally produced mutations, 100% identical. The only difference is that clones are produced on purpose through advanced bioengineering techniques while identical twins happen as an accident of nature. Identical twins are, in a sense, natural clones.
Assuming their are no mutations the twins wold both have 46 chromosomes. Twins, have the normal number of chromosomes, the only difference between an set of identical twins and two average individual is that twins have identical DNA.
