Of course; identical twins are fertilized from the same sperm and egg, whereas fraternal twins are fertilized from different sperm and egg; thus, fraternal twins would resemble each other no more than regular siblings born at different times.

Were identical twins used in the human genome project?
yes, DNA was mapped from a multitude of humans, different races, twins, and even people with genetic abdnormalities were collected.
If Apple maggot flies appear to be two separate races what makes these races different?
They have different allele frequencies.
Why are some twins identical and some not?
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.
What is the difference between dizygotic twins and monozygotic twins?
Dizygotic twins develop from two separate ova fertilized by different sperm at roughly the same time, they are also called fraternal twins. Monozygotic twins develop from one zygote that splits apart producing genetically identical zygotes; also called identical twins.
Do twins have different fingerprints?
Yes. Two people cannot have the same fingerprints. Not even identical twins have exactly matched fingerprints. <3
Why Can fraternal twins be different gender but identical twins are always the same gender?
fraternal twins have two different chromosomes
Were identical twins used in the human genome project?

Has twins ever been born in two different years?
Twins have never been born in two different years.
Do identical twins develop from two different eggs that are fertilized by different sperm?
No, fraternal twins do.
If Apple maggot flies appear to be two separate races what makes these races different?
They have different allele frequencies.
Why can fraternal twins different genders but identical are always the same gender?
fraternal twins have two different chromosomes
How may types of twins are there and which type may have different sex?
There are two types of twins -- monozygotic ("identical") from a single egg, and dizygotic (fraternal) from two eggs. Only dizygotic twins can have a different sex.
What do you call identical twins that develop from two different eggs that are fertilized by different sperm?
That isn't possible: if the twins are from two different eggs, fertilized by different sperm, then they will not be identical. It's genetically impossible.
What is sentence of appearance?
the two twins had different appearance.
Why do some twins look different?
Fraternal twins occur when two fertilized eggs are implanted in the uterine wall at the same time. When two eggs are independently fertilized by two different sperm cells, DZ twins result. The two eggs, or ova, form two zygotes, hence the terms zygotic and biovular.Identical twins occur when an egg splits into two; which makes them identical. Identical twins are not hereditary like fraternal twins can be. It is complete coincidence.
Why are some twins identical and some not?
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.
What is the difference btween identical twins and fraternal twins?
Identical twins are the result of a single fertilized embryo splitting in two at an early stage and forming two viable embryos. As such, identical twins have identical DNA. Fraternal twins are the result of two distinct fertilized embryos being viable. As such, they have different DNA. They could even be different sexes.
