Twins from different eggs are fraternal twins. They are siblings with the same birthdate. They are twins, but not identical, and can even be girl and boy. It is the same process taking place as a single child that a woman becomes pregnant with, but the process happens with two children at the same time. The woman releases two eggs that month instead of one, and they both are fertilized. That is how this type of twin is produced.

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
Which type of stem cell are fertilized eggs?
Pluripotent
How are identical twins created or formed?
There are two way twins are formed. Twins can form by two eggs being released by the female and the sperm will fertilize both eggs. The other way twins can be formed is if one fertilized egg divides and forms two eggs.
How do you know what kind of twins they are?
Genetic testing is the only way to positively identify what type of twins you are having. Identical or monozygotic (MZ) twins occur when a single egg is fertilized to form one zygote (hence, "monozygotic") which then divides into two separate embryos. Half-identical or semi-identical twins (also referred to as "half twins") are the result of a very rare form of twinning in which the twins inherit exactly the same genes from their mother but different genes from their father. Fraternal or dizygotic (DZ) twins (also referred to as "non-identical twins" and in cases of females, occasionally sororal twins) usually occur when two fertilized eggs are implanted in the uterus wall at the same time. When two eggs are independently fertilized by two different sperm cells, fraternal twins result.
Which type of twin are created when two ova are fertilized by two sperms?
dizygotic or non-identical twins
Is your glofish pregnant?
Only live bearing fish get pregnant and Glo fish being a type of danio are egg layers therefore the eggs are fertilized and develop outside the fish's body. So no Glo fish is ever going to get pregnant
How will the arowana fish hatch eggs?
Arowanas are mouth breeders, that is, the male will carry the fertilized eggs in his mouth and protect the young once they hatch. See the link below for a good overview of this fish's reproductive habits.
What is a fraternal sibling?
The most common type of multiple pregnancy. Fraternal twins occur when two different eggs are fertilized by different sperm. Because these types of siblings do not share any of the exact genetic material, they will be no more alike than siblings born at separate times.
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 is The scientific name for identical twins.?
Identical twins (monozygotic) occur when a single egg, fertilized by a single sperm, splits into two identical halves. Two separate babies with identical DNA are formed. Identical twins are always the same sex and blood type. http://www.twin-pregnancy-and-beyond.com/identical-twins-or-fraternal-twins.html
What is the name of a fish offspring?
It varies depending on the type of fish. For many, female fish lay eggs. The eggs are fertilized by the male fish outside the body of the female after they are laid. The eggs grow into baby fish.
What is the frequency of monozygotic twins versus dizygotic twins following IVF?
The type of twins created following IVF are Dizygotic. These are twins resulting from the fertilisation of two separate eggs by two separate sperm. Monozygotic twins are the result of a single egg dividing after fertilisation. http://twinstips.com
