Apart from the obvious that it would suck if everyone was the same and you wouldn't fancy anyone, in genetically identical organisms they are all susceptable to the same diseases.

Is it possible for two people to have the same combination of genetic traits?

Yes. Monozygotic twins, also known as identical twins, are genetically identical because they come from the same zygote (fertilized ovum). Early on, during cell reproduction to form the embryo, the cells separate into two groups, which form two embryos genetically identical to one another. Therefore, they would have the same combination of genes and genetic traits. There are also cases of identical triplets, quadruplets, and quintuplets, all of which came from a single zygote, and are therefore genetically identical. The first known identical quintuplets to survive infancy were the Dionne quintuplets, born in Canada in1934.Yes.

Do cells are genetically identical?

Cells form new cells with identical genetic composition through mitosis. This essentially involves the cell producing enough resources for two cells and then splitting it's membranes into two separate and distinct bodies.


Are cells in a streptococcus chain of bacteria all genetically identical?

Yes. I had this exact question on a quiz and got it correct.


What is a cell that forms in ferilization?

The first cell to form in fertilization is the zygote. The zygote undergoes cell reproduction in order to form a multicellular embryo, in which all of the cells are genetically identical to the zygote. All of the body cells in the new offspring will, in theory, be genetically identical, unless uncorrected mutations occur.


To what degree are all humans identical at the genetic level?

97%


When would having all generations of an organism genetically identical be helpful to a species?

Theoretically, when an organism has adapted perfectly to a completely static situation. Only such a situation doesn't exist in actuality.


What Is an organism cell or piece of genetic material that is genetically identical to one from which it is derived?

That cell is a clone of the first. This happens all the time in your body.


What will you become when your cells are all the same?

A collection of single celled organisms. Or I suppose a newly fertilized egg and sperm would make many identical cells initially. Humans can't be made up uniformly of identical cells.


Why all human beings are not of same colour?

Genetically, humans have different pigmentation in their skin that cause them to have different tints.


When a cell undergo mitosis?

two genetically identical cells.


What are the differences and similarities between skeletons of human beings and chimpanzee?

Due to common evolutionary ancestors and them being genetically close to humans the skeletons are nearly identical. The differences are in bone sizes and dimensional variances such as in the skull, hand and feet.


How does a daughter cell compare to the parent cell after undergoing mitosis?

A daughter cell and its parent cell are exact copies of each other.
