Identical twins come from one egg and one sperm. Fraternal twins come from two eggs and two sperm.
Identical twins are called monozygotic. Fraternal twins are called dizygotic.
Two eggs and Two Sperm.
If a boy and a girl are twins, they are known as fraternal twins. Fraternal twins result from the fertilization of two separate eggs by two separate sperm cells, whereas identical twins result from the fertilization of a single egg by a single sperm cell that later splits into two embryos.
No, fraternal twins do.
Female twins that are not identical are called fraternal twins. Fraternal twins occur when two separate eggs are fertilized by two separate sperm. Maternal twins refer to twins that share the same mother but can include both identical and fraternal twins.
They would be fraternal twins. Identical twins are created when one sperm fertilized one egg, and hat egg then splits in two. Identical twins are always the same gender, while fraternal twins can be either gender, or a mix of the two.
Brittany and Cynthia Daniel are fraternal twins. Unlike identical twins, who share the same genetic makeup, fraternal twins arise from two separate eggs fertilized by two different sperm cells. The Daniel sisters have distinct physical features and differences in their appearances, which is characteristic of fraternal twins.
To keep it simple and not get too technical, fraternal twins are from two eggs and two sperm that independently combine to produce a baby. Identical twins come from a single egg and sperm that divide to create two separate children. Gender is controlled by the males sperm and whether it contains the male genetic X chromosome. Since identical twins have the same sperm their genetic makeup is exactly the same (same egg and sperm used in development). Fraternal twins have two separate sperm and therefore it is possible one has the X chromosome and other does not.
Yes. Identical twins started out as one egg and one sperm cell and are genetically identical. Fraternal twins come from two eggs and two sperm cells and are no more closely related than any other sibling.
Identical twins are genetically the same, because they come from the same fertilized egg/sperm cell zygote, which happens to split into two viable zygotes. Fraternal twins, however, come from two different egg/sperm cell zygotes, that are concurrently fertilized and remain viable.
Fraternal twins, who come from two eggs, are formed when two separate eggs are fertilized by two separate sperm. In all other aspects, their development is the same.
