*Dizygotic twin* is the scientific term for fraternal twins. It means two separate eggs were fertilized by two separate sperm. So, they're basically siblings born at the same time, sharing about 50% of their DNA. They can be the same sex or different sexes. They're genetically no more alike than any other siblings. They are just as genetically similar as normal siblings, not identical copies.
The word *dizygotic* comes from Greek roots. *Di-* means 'two,' and *zygote* refers to the cell formed by the union of an egg and sperm. So, *dizygotic* literally means 'two zygotes.' It highlights that these twins originated from two separate fertilized eggs. This distinguishes them from monozygotic (identical) twins, who come from one zygote.
Think of the Phelps twins who played Fred and George Weasley in the *Harry Potter* movies. They are *dizygotic twins* in real life. Although they have a strong family resemblance, they are clearly distinct individuals. This reflects how *dizygotic twins* share genes like any other siblings but aren't genetically identical.
Now you have a fancy scientific term for fraternal twins! *Dizygotic twin* is great for biology class or impressing your science teacher. Add it to your science vocabulary arsenal! 🔬
