No. Not even close. Fraternal twins result from two eggs fertilized by two sperm at about the same time and being implanted in the uterus together. They are siblings.
Not even identical twins, by the way, can be considered as clones, because cloning involves the removal of genetic information from one cell with its transfer to another cell. Identical twins involve splitting, not cloning.

No, fraternal twins are not clones. Fraternal twins occur when two separate eggs are fertilized by two separate sperm, resulting in two genetically unique individuals. Clones are genetically identical individuals created through asexual reproduction or artificial techniques like somatic cell nuclear transfer.
No that's why theyre called fraternal twins. Identical twins are identical (share the exact same genes) while fraternal twins are as similar to each other as normal siblings are.
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.
If two fraternal twins have the XY sex chromosomes, they will be male.
Identical twins are called monozygotic. Fraternal twins are called dizygotic.
Fraternal twins do not necessarily write with the same hand. Hand preference is influenced by genetics and environmental factors, so it is possible for fraternal twins to have different dominant hands.
The only way to definitively determine if twins are identical or fraternal is through genetic testing. Identical twins share 100% of their DNA, while fraternal twins share about 50% on average, just like regular siblings. Physical similarities alone are not enough to distinguish between the two types of twins.
