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.
Are identical twins always the same size and birth weight?
No
Who is responsible for sex determination in humans the male or female?
When twins are the result of two eggs being fertilized at the same time (non identical twins) there is some evidence to show that there is a genetic basis for this kind of twins. However, it is only their mother that has any effect on the chances of having non identical twins; there is no known mechanism for a father to cause the release of more than one ovum When twins are the result of the zygote splitting into two embryos (identical twins) then this is considered a random act nobody is responsible.
Who are clones fraternal twins or identical twins?
Identical twins, due to the fact that the one fertilized egg splits, have identical DNA. Fraternal twins, since they are from separate eggs, have different DNA.
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 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 identical twins a result of asexual reproduction?
No.
What is the difference btween identical twins and fraternal twins?
Identical twins are the result of a single fertilized embryo splitting in two at an early stage and forming two viable embryos. As such, identical twins have identical DNA. Fraternal twins are the result of two distinct fertilized embryos being viable. As such, they have different DNA. They could even be different sexes.
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.
Are identical twins always the same size and birth weight?
No
What are fraternal twins?
Fraternal twins are two siblings that have the same birth day, but do not look identical.
What is the difference between a fraternal twins and identical twins?
If two (or more) eggs are fertilised and develop together you will get fraternal twins. Identical twins are the result of a single fertilised egg dividing into two embryos.
What do twins have in common?
Identical twins are identical because they both came from the same egg. The term "Identical" is used as they look very much like each other and anybody can say that they are twins by just looking at them.
What are the chances of identical twins having twins themselves?
Women who are themselves fraternal twins have a 10% chance of producing twins, identical twin women have only a 0.6% probability of having a twin birth.
What are two horses with identical genes called?
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.
Why identical twins are similar?
If they were not then they would not be called identical twins!
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.
