monozygotic twins do not run in families
Identical twins, due to the fact that the one fertilized egg splits, have identical DNA. Fraternal twins, since they are from separate eggs, have different DNA.
Identical twins are more likely to occur from a single fertilized egg splitting into two embryos, resulting in genetic duplicates. Fraternal twins result from two separate eggs being fertilized by two different sperm cells. Identical twins are not influenced by genetics or family history, whereas fraternal twins can be influenced by both maternal and paternal genetics.
Because the mother identical twins each have a different husband . . . half of his characteristics show up in their babies.
Identical offspring are referred to as "monozygotic twins" or simply "identical twins." They arise from a single fertilized egg that splits into two embryos, resulting in genetically identical individuals. This contrasts with "dizygotic twins," or fraternal twins, which develop from two separate eggs fertilized by two different sperm. Identical twins share the same genetic material, while fraternal twins do not.
(Person that asked the question)-Once twins are born, and old enough to determine whether they are identical or fraternal, how do you know if they are identical, or just fraternal twins that look identical? I was just curious.
if twins run in the family u are more likely to have twins but most likely fraternal because identical twins are just a very unique coincidence
There really isn't a 'gene' for twins. However, fraternal twins are the result of a woman releasing two eggs at a time. This trait can run in the womens side of the family so there is more chance her daughters will release 2 eggs at a time. To date there is no indication that identical twins have any genetic markers. All women have a chance of having their eggs split and having identical twins.
It depends on what has caused the twins in your family. Having identical twins is a random event, and so there is no genetic or inheritable cause for that. So if there are identical twins in your family, then you are no more likely than anyone else to have twins. If, however, you have non-identical twins in your family, then this could be due to hyperovulation, which can be inherited. This is when a woman is more likely to release multiple eggs during her ovulation cycle, and so a man inheriting this gene will not affect his own chance of having twins. It could effect a woman's chances, but it's still not a sure thing.
Yes - very possibly as twins run in the family.
non-identical twins sometimes run in families down your mother's side. So if you mum or her mum had non-identical twins there's a slightly higher chance you might (if you're female - it makes no difference for men!)
The reason why some twins are identical and some are not starts in utero. Identical twins occur when one egg is fertilized and it splits to create two embryos. Nonidentical twins come from different fertilized eggs.
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.
Fraternal (non-identical) multiples caused by the mother releasing (or being implanted with) two or more eggs… the father has no influence in the connection fraternal multiples! Identical multiples are just a miracle of nature when the egg splits two or more times, it is not generally considered a genetic trait. You chance would only increase if you were one of a naturally conceived triplet (with at least one fraternal).
If they were not then they would not be called identical twins!
No. Twins happen randomly, but if there is a high number of twins in the family, you are likely to have twins.
If their genetic makeup is identical then they are identical twins.
Approximately 30 of twins are identical, also known as monozygotic twins.
