are triplets fraternal or identical?
446741
Identical twins or triplets have the same genetic identity, are always the same sex, and look almost exactly the same. Fraternal multiples develop from separate eggs that are each fertilized by a different sperm.

Fraternal twins really aren't any different than two siblings (except they happened to share the same womb at the same time). Each of these twins is the result of a separate egg being fertilized by a separate sperm. ... And since brothers and sisters can have different blood types, so too can fraternal twins.

Genetics can definitely play a role in having fraternal twins. ... However, for a given pregnancy, only the mother's genetics matter. Fraternal twins happen when two eggs are simultaneously fertilized instead of just one. A father's genes can't make a woman release two eggs.

“They can be either fraternal, resulting from fertilisation of 4 eggs with 4 sperm, or identical, resulting from a fertilisd egg that splits into 2 or more embryos, or a combination of these,” she says. “In the case of fraternal quadruplets the babies can be of any sex, and they will not be identical.

If your first set of twins were fraternal, then your chances of having another set of fraternal twins is multiplied by four! That's 1 in 12! If your first set of twins were identical, then your chances of having another set of identical twins drops way down to 1 in 70,000 or so.

Fraternal twins are formed when two eggs meet two sperm in the womb. Each is fertilized independently, and each becomes an embryo. With identical twins, one egg is fertilized by one sperm, and the embryo splits at some later stage to become two.

Identical triplets or quadruplets are very rare and result when the original fertilized egg splits and then one of the resultant cells splits again (for triplets) or, even more rarely, a further split occurs (for quadruplets). The odds of having identical triplets is unclear.

Identical twins share all of their genes and are always of the same sex. In contrast, fraternal, or dizygotic, twins result from the fertilization of two separate eggs during the same pregnancy. They share half of their genes, just like any other siblings. Fraternal twins can be of the same or different sexes.

Chromosomes from the father's sperm determine gender: XX for a girl and XY for a boy. 2﻿ As a result, the chances of fraternal twins resulting in boys, girls, or a combination are the same as for any other baby. Monozygotic—identical—twins, on the other hand, are always the same gender, either two girls or two boys.

Having identical twins is not genetic. On the other hand, fraternal twins can run in families. Genetics can definitely play a role in having fraternal twins. For example, a woman that has a sibling that is a fraternal twin is 2.5 times more likely to have twins than average!

5﻿ Monozygotic (identical) twins will have the same blood type, with a few very rare exceptions. Dizygotic (fraternal) twins may have the same blood type, or they may have different types. Therefore, it may be concluded that twins with differing blood types are dizygotic, or fraternal.

In the case of identical triplets or quadruplets, the single fertilized egg splits into three or four genetically identical eggs, Herman said. It's unknown why a fertilized egg sometimes splits, but identical twins tend to run in families, indicating that there's a genetic component, Herman said.

It is true that identical twins share their DNA code with each other. This is because identical twins were formed from the exact same sperm and egg from their father and mother. (In contrast, fraternal twins are formed from two different sperm and two different eggs.)

Same-sex twins with separate placentas can be fraternal or identical. For health reasons, it's good to know whether your twins are fraternal or identical. To find out whether twins are identical or fraternal, you can ask for a genetic test after your babies are born.

They May Not Look and Act Alike Fraternal twins, on the other hand, are as alike as any two siblings. They may look very different. They can have different hair color, eye color, stature, and personalities.

After all, while huge differences can and do happen with fraternal twins, identical twins are usually exactly that -- identical in skin, hair and eye color. But, actually, twins who start out with identical DNA always have slightly different DNA by the time they're born.
