Is it possible for two persons to have exactly the same genotype?

Phenotype refers to "what the organism looks like to the naked eye". You can think of it as - "If I look at that organism, what does it LOOK like? Is it tall, short, wrinkled, smooth, etc..".
Genotype refers to "what are the genetic reasons for why that item looks the way it looks?" Are the Alleles (one of the member of a pair or series of genes) homozygous or heterozygous? If an organism Alleles are homozygous it means that they are purebred for either the recessive or dominant trait (FF or ff). If an organisms Alleles are heterozygous for a specific trait it is due to a hybrid pairing (Ff).
Thus you could have 2 different organisms that have a phenotype of being TALL, but the reason for that could be based on a genotype of either Tt or TT (where T is the dominant trait for tallness).

∙ 14y agoA Phenotype corresponds directly corresponds to a genotype. Basically it determines your physical traits based on the data that your genes contain. So, no they can not have different phenotypes if they have the same genotypes.
Wiki User
∙ 13y agoYes it is definitely possible for two individuals to share the same genotype by different phenotype. The mere presence of a gene will not confer the characteristics unless it is active. many time genes tend to skip generations and also activate at random. There are many identical twins who look different in some way as a proof of this possibility.
Wiki User
∙ 14y agoYes, it could, an example of this is, are identical twins because they have the same physical features and the same karyotype.
Wiki User
∙ 14y agonope...but identical twins can be upto 99.9% similar
Wiki User
∙ 10y agoYes. If you are heterozygous or homozygous dominant, two individuals can have the same phenotype but different genotypes.

Can two organisms have the same genotype?
Yes.If* two or more organisms are formed from the same original cell, and* all divisions of that cell are by mitosis, and * there is no mutation, then the organisms will be genetically identical (= have the same genotype).Some examples:* human identical (monozygotic) twins * individuals of Hydra, a freshwater coelenterate, formed by budding * plants formed by vegetative propagation, such as budding (e.g. fruit trees in horticulture) and forming stolons (e.g. strawberries naturally)
What describes organisms or genotypes that are homozygous for a specific trait that always produce offspring of the same phenotype?
Yes, homozygous with homozygous (both the same genotype) will produce homozygous of the same genotype
Can the genotype for a gray bodied fly be determined?
Well, in order for us to get a accurate genotype, we would need to know the parents. What are their traits?
Which is not true of an organism's genotype?
If an organism is a true-breed, the organism's genotype would be homozygous. "Homo" is the same and the alleles in a true-breed are identical.
What is the man's genotype?
The man's genotype is CcFf. The woman's genotype is CcFf. These genotypes only apply if curly hair is dominant to straight hair. Freckles is dominant to no freckles. Also if a man who is heterozygous for both curly hair and freckles who then marries a woman with the same genotype.
Is it possible for 2 persons to have exactly the same observable treats?
yes and it's traits
What percentage of possible types of offspring had genotype of the same genotype as the parent?
75 percent
How many of the possible types of offspring had the same genotype as the parent?
56
What perentage of the possible types of the offspring had the same genotype as the parents?
75%
What two genotypes are possible for a dog that has black fur?
No. They might have the same phenotype, but would not have the same genotype.
How is possible for two individuals to have the same phenotype but different genotype for a trait?
it is possible beccause you dont always need both
How its possible two individuals to have to the same phenotype but different genotype for a trait?
it is possible beccause you dont always need both
What percentage of the possible types of offsprings had the same genotype as the parents?
That depends entirely on the genotypes of the parents.

Can 2 organisms have different genotypes but the same phenotype?
No. It is possible for the reverse to be true, two organisms can have the same phenotype but a different genotype. This is because the phenotype is what you will see on the outside whereas the genotype is the combination of alleles and since this determines the phenotype, two organisms with the same genotype will have the same phenotype. So, basically, no. Actually 2 organisms can certainly have different phenotypes with the same genotype--this refers to the concept of penetrance. Some people can have the gene for a condition but never show symptoms. An excellent example of this is the disease neurofibromatosis. This disease has very variable penetrance in which a child of an affected parent may show no signs of the disease, but then have a child with a severe form.
Why it is difficult to exactly predict someone's traits even if you know their genotype?
genes are mixed around during sexual reproduction, and it ensures that the genes will not be the same.
How can two individuals that have the exact same genotype for a certain trait but not identical when it comes to that trait be possible?
I have the same Bio Question. I THINK it depends on how your DNA reads the genes available.
