Yes, if it is one egg that splits after fertilization from one sperm then the two eggs are identical twins.

If an egg is fertilized by a sprem containing a y chromosome the fertilized egg?

If an egg is fertilized by a sperm containing a Y chromosome, the resulting fertilized egg will develop into a male organism. This is because the presence of the Y chromosome determines the development of male characteristics.


What are the gender statistics for identical twins?

Identical twins are always the same gender, either both male or both female. This is because they come from a single fertilized egg that splits into two embryos.


Why are identical twins identical and fraternal twins are not?

Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.


Are identical twins developed from one egg or two?

There are at least three ways to produce twins. One is when the female produces two eggs, both of which are fertilized by the male. This is how fraternal twins are produced. Fraternal twins can be both the same sex or different sexes. Fraternal twins may only bear a slight resemblance to one another, no more than any two siblings might. (Fraternal twins can actually have different biological fathers, because the eggs may be produced a day or two apart.) Another is for the woman to produce one egg which is fertilized by the male, and then the egg divides into two. This is the traditional way that so-called identical twins are produced. Identical twins are always the same sex. (I use the term 'so-called,' because they are actually 'mirror image' twins.) A third way is for the woman to produce one egg, which then divides into two, which are both subsequently fertilized. There is a greater chance that such twins will resemble one another than fraternal twins, and they may be the same or opposite sexes.


Can an egg be fertilized by another egg?

No, an egg cannot be fertilized by another egg. Fertilization occurs when a sperm cell from a male organism combines with an egg cell from a female organism to form a zygote.

What is it call when twins are fertilized into two separate cells?

Dizygotic twins. If they were fertilized in the same egg, they would be called monozygotic twins.


How does a girl give birth to twins?

The fertilized egg is divided into two fertilized eggs, and they both become twins.


How many egg cells are used with twins?

It depends on the type of twins If It was identical (monozygotic) twins, one egg is fertilized (As you can see, identical twins have similarity in phenotype (the observable characteristic of an organism) because of development of one zygote divided into two embryos) but if it was non-identical twins, two eggs or more (such as triplets or quadruplets) are fertilized. The twins have differences in phenotype


What is the difference fraternal and identical twins?

Identical twins come from the same fertilized egg; fraternal twins come from 2 fertilized eggs.


Do fraternal twins develope from a single fertilized egg?

No.


What is identical and what is fraternal?

Why are the twins identical?

Twins are not necessarily identical. They can be fraternal as well. Identical twins result when one fertilized egg splits in two. Fraternal twins result from two fertilized eggs.

Are non-identical twins occur when egg cells turns into embryos on their own?

No, non-identical twins are fraternal twins. They are created when two eggs are fertilized at the same time and become embryos. Identical twins are when a fertilized egg splits into two on its own.


Are the olson twins futurnal?

They are not fraternal twins (two different fertilized eggs implanted), they are identical twins (one single fertilized egg which divide into two separate embryos)
