Non identical twins are formed when the mother releases two eggs and both those eggs are fertilised. hope this helps :)

∙ 14y agoIdentical twins are also known as monozygotic twins, and they are fertilized when one single egg from just one zygote divides into 2 embryos, therefore they are usually the same sex, and they have very similar DNA, so to answer your question, most of the time, yes. Unless, there was a mutation during the development which would cause different phenotypes (which would make them look different).

∙ 13y agoYes. Mitosis is the process in which cells reproduce or divide, and cytoplasmic division is a part of that process. The steps of mitosis are as follows:
-Prophase
Nuclear envelope disappears
-Metaphase
Chromatids align
-Anaphase
Chromatids separate, centromeres divide
-Telophase
Cytoplasmic division occurs in this phase, then the chromatin expands.

Do monozygotic twins have the same genotype and phenotype?
Monozygotic twins are two offspring that have identical DNA. This is because they arose from one zygote (hence monozygotic). Both of the offspring came from this zygote which at a particular time spilt. After the split, each individual had a copy of the original DNA
Are monozygotic twins opposite sex?
No, monozygotic twins would be the same sex. Monozygotic twins come from one single fertilized egg, or zygote, which then splits to create two separate zygotes which will be genetically identical, or "identical twins", which will always be of the same gender.
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 are two individuals that develop from the same zygote called?
Two individuals that develop from the same zygote are called identical twins. If they develop from two separate zygotes, they are fraternal.
How are sets of identical twins made?
Identical twins, or monozygotic twins are formed from one zygote. This is usually a result of damage to the embryo that causes it to split into two. If both halves are big enough to survive and the split has happened early enough on then two badies sharing one amniotic sac, one placenta and the same DNA will be born.
What are conjoined twins?
Identical twins born with their bodies joined at some point and having varying degrees of duplication, a result of the incomplete division of the zygote from which the twins developed. Also called diplosomia.
A zygote that separates into two clusters of cells insted of just one prduce?
Non identical twins.

How are twins produced?
identical twins are formed when one sperm fertilizes a single ovum and the zygote divides into two in the initial stages of cleavage of the zygote. then, the two parts of the same zygote develop independently. fraternal wins are formed when two sperms fertilize two different ova.
How twins and multiple births are produced?
WHENE the division of the zygote is not complete,is pairs of siamese twins who maybe joined at the buttocks,chest,neck.
What happens to a pregnant women for her to have twins?
Twins can be identical or fraternal (monozygotic or dizygotic). For identical twins, one sperm fertilizes an egg. The zygote divides into two identical embryos. For fraternal twins, two separate eggs are fertilized. They both implant on the uterine wall, forming two zygotes.
What are two individuals that develop from the same zygote called?
Two individuals that develop from the same zygote are called identical twins. If they develop from two separate zygotes, they are fraternal.
How can you get a twin baby?
It is possible to have twins through in vitro fertilization, but "monozygotic" or identical twins are just a fortunate accident of nature which happens when a zygote splits.
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.
When a zygote splits into two individual cells the creation of identical cells or what is created?
Identical twins.
