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?
Identical twins may not always be the same size and birth weight. Factors such as position in the womb, nutrition, and other environmental influences can lead to differences in size and weight at birth.
How many pairs of identical twins are in The world?
Estimating the exact number of pairs of identical twins in the world is challenging due to varying birth rates and reporting practices across countries. However, studies suggest that approximately 3 to 4 pairs of identical twins are born for every 1,000 births globally. Given the world's population and average birth rates, this could translate to millions of pairs of identical twins existing today. The prevalence of identical twins can also vary by region and population genetics.
Which kind of twins are identical or non-identical are more like two children born at different times?
Non-identical twins are more like normal siblings. Identical twins have the exact same DNA, so will be very similar in appearance. Their environment will cause them to have very slight differences, such as different fingerprints and freckles.
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.
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.
What are fraternal twins?
Fraternal twins are two siblings that have the same birth day, but do not look identical.
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 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.
Are identical twins always the same size and birth weight?
Identical twins may not always be the same size and birth weight. Factors such as position in the womb, nutrition, and other environmental influences can lead to differences in size and weight at birth.
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.

The prevalence of identical twins can also vary by region and population genetics.
If a boy and a girl are twins are they faternal twins or twins?
If a boy and a girl are twins, they are known as fraternal twins. Fraternal twins result from the fertilization of two separate eggs by two separate sperm cells, whereas identical twins result from the fertilization of a single egg by a single sperm cell that later splits into two embryos.
