Why are identical twins not clones of their parents?
Children are the results of a mix of their parent's DNA. They do not have the exact same DNA, they have half their mother's and half their father's. Character and personality play a major part in allowing anyone to identify a person - particularly parents, who spend a lot of time with, and have a lot of opportunity to observe the differences between, their children.
Did the two DNA molecules have exact copies of each other?
Yes, two DNA molecules that are exact copies of each other are known as sister chromatids and are produced during the S phase of the cell cycle through DNA replication. Each sister chromatid contains the same genetic information as the other.
How many copies of each gene do you have and where do they come from?
Humans typically have two copies of each gene, one inherited from each parent. This diploid structure allows for genetic diversity and variation. However, some genes can have multiple copies due to duplications or variations in certain individuals. The specific number of gene copies can vary between individuals due to genetic mutations or polymorphisms.
Which feature do indenticil twins differ from each other?
Identical twins can differ from each other in terms of their personalities, life experiences, interests, and even health conditions despite sharing the same genetic makeup. These differences can be influenced by environmental factors, random variations in developmental processes, and interactions with other people.
Why can twins resulting from a single fertilized egg exchange blood or receive organ transplant from each other without rejection while twins resulting from two fertilized eggs sometimes cannot?
It is because identical twins resulting from the same fertilized egg (zygote) are actually the same individual. All the DNA in all their cells is 100% identical. They are clones. Transplantation between the two of them is equivalent to donating your own organs to yourself. Fraternal twins (from two separate zygotes) are not identical and are not the same individual. They are however more closely related to each other than they are to either of their parents.Twins resulting from one single fertilized egg carry exactly the same DNA. They are exact copies of each other (medically, anyway). Twins from two different eggs, although are twins, do not share the same DNA (since each egg carries different genes), hence are not completely compatible for organ transplantation (without additional immunosuppression).
Why twins are not identical?
By convention, a clone is an engineered offspring derived from the genetic material of a single adult. Identical twins are genetic copies of each other, but they were formed by the splitting of a fertilized zygote rather than by extracting the genetic material of a single adult.
What correctly describes the similarities between identical twins?
They are as similar as any other two siblings.
What correctly describes the similarities between fraternal twins?
They are as similar as any other two siblings.
What is a good analogy for sister chromotid?
A good analogy for sister chromatids is like a pair of identical twins, where each twin carries the same genetic information. Just like how twins are born from the same fertilized egg, sister chromatids are formed during DNA replication as exact copies of each other.

A sentence for identical twins?
Identical twins develop from a single egg that splits into two.Identical twins can be so similar that their parents cannot tell them apart.
Did the two DNA molecules have exact copies of each other?
Yes, two DNA molecules that are exact copies of each other are known as sister chromatids and are produced during the S phase of the cell cycle through DNA replication. Each sister chromatid contains the same genetic information as the other.
In maths what objects are exact copies of one another?
If two objects are exact copies of each other, they are said to be congruent.If two objects are exact copies of each other, they are said to be congruent.If two objects are exact copies of each other, they are said to be congruent.If two objects are exact copies of each other, they are said to be congruent.

Do sister chromatids have half the amount of genetic material as the original?
No, sister chromatids have the same amount of genetic material as the original chromosome. They are exact copies of each other formed during DNA replication. Each chromatid contains a full set of genetic information.
