Not always. Even identical twins will experience some differences in development before birth. However, it is unlikely that the shape of twins' ears would be radically different, even in most fraternal twins.
No, Esau and Jacob were not identical twins. They were fraternal twins, meaning they were born from the same pregnancy but did not have the same genetic makeup.
Twins can have identical chromosomes if they are monozygotic (identical twins) because they develop from a single fertilized egg that splits into two embryos. This results in both twins having the same genetic makeup and identical chromosomes.
Homozygous means "the same egg." That refers to identical twins. Identical twins are always the same gender since they have the same 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.
Twins are identical because they come from the same egg.
It is not possible for twins with different eye colors to be identical. Differences in eye color indicate genetic variation, meaning the twins are fraternal (non-identical). Identical twins come from a single fertilized egg and share the same genetic makeup, including eye color.
do identical or non identical twins share the same placenta
The same as when you had the first set of identical twins.
No, Esau and Jacob were not identical twins. They were fraternal twins, meaning they were born from the same pregnancy but did not have the same genetic makeup.
No, twins in the same placenta are not genetically identical. While identical twins share the same DNA, they may have slight genetic differences due to mutations that occur after fertilization.
identical twins do. just not the same fingerprints.
yes they are... simmes twins form from one egg that is in the process of separating into two eggs or identical twins... but the process isn't finished and that is why they are "stuck together"
Identical twins.
No, they are ferternal. They have different colored eyes and one used to be shorter then the other. If you get any of their old movies you can tell. Mary-Kate usually has shorter hair then ashley, but that doesn't make them ferternal.
Identical twins can share the same placenta during pregnancy, but it is not always the case. In some instances, identical twins may have separate placentas.
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.
