Whenever the zygoat (fertilized egg) starts mitosis (cell division) it creates two zygoats. These two zygoats are exactly the same in looks and DNA.

∙ 12y agoThis is not a probability questions but a biological question and, of course, not all sets of twins are identical.
If the twins are identical, this means that a single fertilized egg split in two before it started developing into a fetus. As a result, both twins have identical genetic information. If they are not identical, then this means that two eggs were in the uterus at the same time and that they were both fertilized separately from one another. Thus they almost certainly have different genetic information.

What is one way in which identical and fraternal similar?
Identical and fraternal twins typically share many similar characteristics
Why identical twins are similar?
If they were not then they would not be called identical twins!
Why are identical twins and fraternal twins not the exact same?
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
Why are the twins identical?
Twins are not necessarily identical. They can be fraternal as well. Identical twins result when one fertilized egg splits in two. Fraternal twins result from two fertilized eggs.
Why are Identical and fraternal twins similar?
They are twins!
Why wont the babies look the same if identical twins have babies with identical twins?
Because the mother identical twins each have a different husband . . . half of his characteristics show up in their babies.
What is one way in which identical and fraternal similar?
Identical and fraternal twins typically share many similar characteristics
How many different kid of twins are there?
There are two main types of twins: identical (monozygotic) twins, who form from a single fertilized egg that splits into two embryos, and fraternal (dizygotic) twins, who develop from two separate eggs that are fertilized by two separate sperm. There are also rarer types of twins, such as mirror-image twins and conjoined twins.
What are two horses with identical genes called?
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.
How are twins born non-identical?
Non-identical (fraternal) twins are born when two separate eggs are fertilized by two separate sperm. This results in siblings with different genetic makeups and physical characteristics. Non-identical twins can be the same sex or different sexes.
Why identical twins are similar?
If they were not then they would not be called identical twins!
Why are identical twins identical and fraternal twins are not?
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
Why are the identical twins different?
Because genes do not account for every trait or characteristic. Some characteristics are influenced by environment.
Why are identical twins and fraternal twins not the exact same?
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
How are twins identical?
Twins are identical because they come from the same egg.
How do you get identical and non identical twins?
Identical twins are formed when one fertilized eggs splits. Non-identical twins are formed when two separate eggs are fertilized.
Do identical twins have identical brains?
Identical twins do not have identical brains. While they may share some genetic similarities, environmental factors and experiences can lead to differences in their brain structures and functions. Studies have shown that identical twins can exhibit variations in brain development and neurological characteristics.
