No
Twins are identical because they come from the same egg.
do identical or non identical twins share the same placenta
The same as when you had the first set of identical twins.
if they share 1 heart then yes they do. but if they have different hearts then they do not
identical twins do. just not the same fingerprints.
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.
Homozygous means "the same egg." That refers to identical twins. Identical twins are always the same gender since they have the same chromosomes.
No. All identical twins are the same sex. Judith and Hamnet were opposite sexes, and so were fraternal twins.
fraternal twins have two different chromosomes
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.
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.
