Usually but not always. They can even be different sexes. Identical twins are fromed from one fertilized egg which splits into two and so genetically they have the same DNA and are therefore identical. Fraternal twins are formed from two separate eggs fertilized by two separate sperm cells, and are called 'twins' simply because they share the womb during their development. Otherwise, they are no more similar than normal brothers, sisters or a brother and sister.
Twins who are of the opposite sex or do not look alike are fraternal twins ~ not identical. This means that at the time of their conception ~ two eggs were fertilised. In the case od identical twins, one egg is fertilised and split in half.
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.
Fraternal twins are created when 2 separate eggs are fertilized. Identical twins are created when 1 fertilized egg splits into 2. It is impossible for one identical twin to be male and the other female. Identical twins are usually the ones that look exactly alike.
The girl and boy twins are fraternal, meaning they are not identical.
Fraternal means "brother-like." Identical twins result from a single fertilzed egg dividing into two separate embryos so the twins share all DNA. Fraternal twins result from two different eggs being fertilized by two different sperm at the same time. The babies are then born at the same time, but only share 25%of their DNA with each other, which is the same amount that siblings born at different times share. The word fraternal used in social organizations, like "the fraternal order of"...refers to the thought that the members are like brothers to each other. Modern french uses the word frere to mean brother.
Ferternal twins don't look alike, but twins do
Yes. Fraternal twins don't look alike at all. Identical, meaning to look the same, are well, identical.
Fraternal twins.

It means 'fraternal twins', the kind that don't look alike. The kind that look alike are called 'gemelos.'
Yes
Yes, non-identical twins are often referred to as fraternal twins. These twins develop from two separate eggs fertilized by two different sperm cells, resulting in genetic differences that can make them look less alike than identical twins.
Fraternal. They develop from separate ova and are not genetically identical, so look different, can have different sex etc. Unlike "identical twins."
Twins don't always think alike, whether they be identical, fraternal, or even simese. It depends on there personalities, not their looks.
Fraternal twins are two siblings that have the same birth day, but do not look identical.
(Person that asked the question)-Once twins are born, and old enough to determine whether they are identical or fraternal, how do you know if they are identical, or just fraternal twins that look identical? I was just curious.
