Luck. There is no way of having identical twins, let alone choosing the sex.
There are two primary types of twins, Identical and Fraternal.
Identical twins occur when the egg splits after fertilization. To date no indication of a genetic link has been found. Anyone has a chance, though small, of having identical twins.
Fraternal twins occur when more than one egg is dropped during ovulation. This trait can be inherited from the mother's side of the family. Studies have shown that the chances are also increased by being overweight or older. Fertility drugs also make this more likely to happen.
No. Conjoined twins are always identical twins. Identical twins are always the same sex.
Any set of twins that are not identical (whether it's boys or girls or a combination of the two) are fraternal twins.
Although there can be the usual resemblance of a family, they cannot be both "identical" twins and different genders.
No. Identical twins are identical. Fraternal twins are not.
Fraternal twins are created when 2 separate eggs are fertilized. Identical twins are created when 1 fertilized egg splits into 2. It is impossible for one identical twin to be male and the other female. Identical twins are usually the ones that look exactly alike.
In identical twins, the DNA is identical, which is what makes them identical. In Fraternal twins it is not.
I don’t Know
Some twins are identical twins, other are not identical twins. Identical twins develop from a single fertilized egg that subsequently splits into two zygotes. Non-identical twins, also called fraternal twins, develop from two different fertilized eggs.
Twins are identical because they come from the same egg.
There are two two kinds of twins.Gametic twins - two sperms fuse with two eggs to form gametic twins.In the case of gametic twins, the twins are not identicaland infact there is a chance for one male and another female.Zygotic twins - zygote forms after fertilisation (Fusion of sperm and egg). The zygote divides in to two cell and these two new cells develops in to twins.In the case of zygotic twins, the babies are identicaland both the twins will be males or females.
No. Conjoined twins are always identical twins, and never just fraternal twins. Identical twins come from a single embryo that splits. In the case of conjoined twins, a complete split never occurs. So when they come from the same embryo, they are always the same gender.
It means, "the female identical twins."
If they were not then they would not be called identical twins!
Yes, they are identical twins, monozygotic twins, born ten minutes apart. They share the same genome, they are identical genetically, they are identical twins.
Identical twins are created when 1 eggs splits into 2. Conjoined twins are the result of identical twins not separating all the way.
Yes. Conjoined twins are always identical (monozygotic) twins, and identical twins are always the same sex.There is a theoretical case where identical twins could be opposite genders, when the babies are female but in one of the females, a branch of one X chromosome breaks away; however, I don't believe this has ever been observed.
do identical or non identical twins share the same placenta
identical twins have the same genes from the same parents. Non identical twins have different genes.
Just that, female conjoined twins. In some languages all nouns have gender, so in French, Les Jumelles Siamesienne, the enne suffix would mean female. By the way, conjoined twins, being also identical twins, are always the same gender.
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.
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.
Identical twins are formed when one fertilized eggs splits. Non-identical twins are formed when two separate eggs are fertilized.
The same as when you had the first set of identical twins.
