Fraternal twins each have their own umbilical cord, just like they have their own sac. The two of them are just the same as two siblings with the same birth date.

Which gender is homozygous?
Homozygous means "the same egg." That refers to identical twins. Identical twins are always the same gender since they have the same chromosomes.
Why does identical twins not have the same weight and Skin colour?
Eye colour is caused by genetics whereas the weight of a person depends on how they life their life (how healthily they eat or how much exercise they do) so it is an environmental variation. Identical twins have the same genes so have the same eye colour.
Do conjoined twins have the same sex?
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 twins have same IQ?
No, even though twins do have identical DNA, they can have far different environments and life experiences. So, two identical twins though genetically the same could be very dissimilar in intelligence.

if they share 1 heart then yes they do. but if they have different hearts then they do not
Do twins share the same umbilical cord?
Fraternal (non-identical) do not share the same placenta as they are two babies formed from two eggs and two sperm. If they implant close together they may appear to be one placenta, but they are not. Identical twins formed from one egg and one sperm may split at any stage from the two cell right up to late in embryonic development which produces conjoined (Siamese) twins. The later in embryonic development the split occurs the more likely they are to share a placent.
Do twins have the same DNA?
identical twins do. just not the same fingerprints.
Which animals are the same?
Identical twins.
Why are identical twins and fraternal twins not the exact same?
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.
Which gender is homozygous?
Homozygous means "the same egg." That refers to identical twins. Identical twins are always the same gender since they have the same chromosomes.
Was Shakespeare's twins identical?
