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.


How do you get identical twins and fraternal twins?

Identical twins are two children born of one egg and one sperm, that splits early on and then separates, each half then developing into a full organism. Since they came from only one egg and one sperm, their genes will be identical. Fraternal twins are two children born of two eggs and two sperms, each of them developing into a full organism. Since they did not come from only one egg and one sperm, their genes will be different. They could even be opposite sexes.


Why are transplant between identical twins be more successful than fraternal twins?

I am in the medical field, and if you need a little more detail....Read on down: Identical twins share an IDENTICAL genotype (genetic make-up). They were the result of a split into two human beings of ONE egg. All of the information on that egg was equally divided to create two people that are identical. The success of ANY transplant is based on how close you can match the genetics. That is why they take samples of blood and marrow, etc., to test. When you are planning to donate organs, they try to type and match the organ to the recipient. Fraternal twins share FAMILY genetics, but not identical genetics. Family that can donate is desired for being "as close as you can get", very often, but Fraternal Twins do not share the exact same genotype. Fraternal twins are from TWO SEPARATE eggs, fertilized by two different sperm. Each egg and sperm carries different information genetically, and the possibilities are endless as far as creation of a human being, because you have eons of genetic history passed down. It is even possible that Fraternal twins--as with any family member--may not be a good match for a recipient. At any rate...with Identical Twins, a transplant is more likely to be successful because it is like taking an organ out of one of your "selves" and putting it back into yourself. It should be a perfect match, and identical to the organ that is being replaced.


What are the genetic priciples of identical twin case?

In the case of identical twins, a single embryo divides into two completely separate and genetically identical embryos. Each embryo continues to grow and develop individually, but with the exact same genes as the other.On an interesting side note: Children of identical twins are genetically as closely related to their parent's identical twin as they are to their identical twin parent. Genetically, both twins are the parent of the other's children. Also, their children are genetically half-siblings.


If they were 32 children split equally into 4 groups how many children were in each group?

Why can fraternal twins be different genders but identical twins are are the same gender?

Identical Twins are the result of a single fertilized egg spliting in two producing two genetically identical children. Fraternal twins are the result of the mother producing two eggs each fertilized by a different sperm from the father. This can result in opposite sex twins.

Do fraternal twins have the same fingerprints?

No, fraternal twins do not have the same fingerprints. Each person's fingerprints are unique and are determined by genetic and environmental factors during development in the womb. This uniqueness applies to all individuals, including twins.

Do twins have one amniotic sack or two?

If you mean identical twins, they can be in one sac (1) or each in their own sac (2). As for fraternal twins, they each have their own sacs (2).

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 fraternal twins have their own placenta?

Identical twins may or may not share the same placenta . Identical twins develop when a fertilized egg splits. Depending on when the split occurs will determine if the twins share a placenta, with either one or two chorions and amnions, or if they each develop their own placentas.


How do fraternal form?

Can twins be two different races?

Yes, it is possible for twins to be different races if each parent is of a different race. This can occur when each parent contributes different genetic traits to the offspring, resulting in twins with varying physical characteristics.
