Are fraternal twins technically clones?
No. Not even close. Fraternal twins result from two eggs fertilized by two sperm at about the same time and being implanted in the uterus together. They are siblings.Not even identical twins, by the way, can be considered as clones, because cloning involves the removal of genetic information from one cell with its transfer to another cell. Identical twins involve splitting, not cloning.
Why indentical twins have the same features?
Identical twins, or in-fraternal twins, are the offspring that look exactly alike and are of the same gender, sharing the same exact genetic information. In-fraternal twins occur when a fertilized ovum (egg) has divided and each went on to become an embryo containing exact same genetic information.
Your friend is pregnant with twins they r in two different sacs and share a placenta and one is a boy and one is a girl?
They are dizygotic. Fraternal twins.
How Do Fraternal Twins Occur and Identical Twins Occur?
Fraternal twins (dizygotic twins) are simply two fertilized eggs that are implanted in the uterus at the same time. Identical twins (monozygotic twins) is one fertilized egg that separates into two embryos. In most cases, identical twins share one placenta, but have separate amniotic sacs. In some cases, they have two placentas. In rare cases, they share both the placenta and the amniotic sac.
Do twins have one amniotic sack or two for humans?
Fraternal twins always have two. About 1% of identical twins share an amniotic sack. 99% will each have their own sack.
Why do you think identical twins were more alike than fraternal twins?
Fraternal twins share most of their genetic material, by virtue of having the same parents. Identical twins, however, by definition share 100% of their DNA. This means, for example, that identical twins cannot ever be one of each gender, as fraternal twins often are.
What is the definition for fraternal twins?
Fraternal twins are twins who develop from two separate fertilized eggs. They can be of the same or different genders and share about 50% of their genetic material. Fraternal twins are also known as dizygotic twins.
Who would have the most genetic similarities identical twins or fraternal twins?
Identical twins would have the most genetic similarities, since they share the same original 46 chromosomes.
How does the genetic makeup of fraternal and identical twins differ?
how does the genetic makeup of a fraternal and identical differ
Are fraternal twins genetic?
Yes, they are genetically related.
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.
What percent of genes do fraternal twins share?
50%

What is one way in which identical and fraternal similar?
Identical and fraternal twins typically share many similar characteristics
What are the odds of having twins twice?
From what i know, if your twins are identical then you have no increased chance of having twins a second time. If your twins are fraternal, you are twice as likely to have twins again because fraternal twins are the result of more than egg being released and that is a genetic trate.
Why indentical twins have the same features?

What is the definition of fraternal twins?
Fraternal twins occur when the woman has released two eggs simultaneously, and they've both been fertilised by different sperm.The babies born will be no more similar to each other than any other set of siblings from the same parents.The other type is identical twins, where there's one egg that for some reason splits and form two individuals. These will usually be very much alike, as they share the exact same genetic material.
