There are two way twins are formed. Twins can form by two eggs being released by the female and the sperm will fertilize both eggs. The other way twins can be formed is if one fertilized egg divides and forms two eggs.
Identical twins are formed when one fertilized eggs splits. Non-identical twins are formed when two separate eggs are fertilized.
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.
Identical twins are formed when a fertilized egg splits in two and separates, creating two embryos. Fraternal twins form when two separate eggs are fertilized.
Identical twins (monozygotic) occur when a single egg, fertilized by a single sperm, splits into two identical halves. Two separate babies with identical DNA are formed. Identical twins are always the same sex and blood type. http://www.twin-pregnancy-and-beyond.com/identical-twins-or-fraternal-twins.html
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.
Identical Twins are the result of a single fertilized egg spliting in two producing two genetically identical children. Fraternal twins are the result of the mother producing two eggs each fertilized by a different sperm from the father. This can result in opposite sex twins.
Yes, identical twins have the same DNA because they are formed from a single fertilized egg that splits into two embryos. This means they share the same genetic information and are genetically identical.
Simply because identical twins have formed from the same egg. Their genetic make-up is identical - so their physical appearance is also the same.
Identical twins are identical because they both came from the same egg. The term "Identical" is used as they look very much like each other and anybody can say that they are twins by just looking at them.
Identical twins.
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.
No, non-identical twins are fraternal twins. They are created when two eggs are fertilized at the same time and become embryos. Identical twins are when a fertilized egg splits into two on its own.
