Q. Why are genetically identical twins different at birth?
The original fertilized egg divides one or more times before the resulting clump of cells splits into two. Each clump of cells goes on to become one of the identical twins. DNA differences or mutations can happen any time a cell divides. This is because a cell needs to copy its DNA before it can divide.
Q. How genetically similar are monozygotic twins?
It is true that identical twins share their DNA code with each other. This is because identical twins were formed from the exact same sperm and egg from their father and mother. While this rarely happens, it makes it so that one identical twin may have a genetic condition, while the other twin does not.
Q. When would monozygotic identical twins be produced?
Monozygotic twins form when a single fertilized egg that splits. From there, two embryos form and will eventually develop into two babies. Monozygotic (“mono” means one and “zygote” means fertilized egg) is the term used to describe this process.
Q. Is one twin always evil?
4. One Twin Is Always the Evil Twin of the Other Twin. The famous legend about everyone having an evil twin is not a completely fictional one. When a set of twins are born, one is always a meaner version of their twin.
Q. Do twins feel jealous?
Twins are competitive with each other and/or jealous of one another because of their unique and deep attachment, which creates judgments. This rivalry is based on the reality that twins measure themselves against each other from an early age.
Q. Should Twins be in same classroom?
1 It’s not that they can’t ever be apart — but when they’re in their younger years they may simply be better off together. While limited research has shown there’s no real benefit to keeping twins together in a classroom versus separating them, ultimately it should be up to the parents to make that call.
Q. Are twins born with the same personality?
Despite having the same genetic makeup, identical twins have their own distinctive personalities. Importantly, identical twins raised in the same household — the same “outer” environment — still develop personality differences over time.
Q. Is the bigger twin born first?
In the majority of vaginal births, Baby A is born first. But occasionally the twins switch positions at the last minute, and Baby B emerges first, as further noted by the Stanford Medicine News Center.
