One way is if an allele for the gene in question is dominant. Homozygotes for the dominant allele and heterozygotes will both have the same phenotype.
Organisms have the same phenotype, or physical characteristics. They do not, however, have the same genotype, or genetic makeup. If T represent tall, and t represnts short then the organism will have the genotypes TT and Tt. If you make a Punnett square you will have the same phenotype but different genotypes. Unless some weird mutation occurs....

How can two plants that have different genotype have the same phenotype?
No they do not. Say for example we are looking at the the colour of pea plants where R represents the allele for the colour red and, and the other allele r represents green. The plant will be red with the genotype RR AND Rr which are different genotypes.
If two genes in a gene pair are for the same trait what will that trait be?
The question should be "If two alleles for a gene are the same, what phenotype will the organism have?" Answer: If the two alleles are for the dominant phenotype, the organism will exhibit the dominant phenotype. If the two alleles are for the recessive phenotype, the organism will have the recessive phenotype.
What is phenotypic variation?
Phenotype variation is slight variations in a phenotype that are caused by the expression of an organism's genes or the influence of environmental factors. A species can have several different phenotypes within it.
Is it possible for two organisms to live in the same habitat but have different niches?
yes it is possible
What is competition in science definition?
When two organisms from different species are after the same resources and food, they are in competition.
What might the phenotypes be of two organisms that were found to have different genotypes but the same phenotype?
Phenotypes refer to the visible traits (or characteristics). Genotypes are the underlying causes for those traits. There may be different genotypes that cause the same phenotype. If the observable traits from one individual are the same from another individual, one can say they have the same phenotypes.
How can you have the same phenotype but a different genotype for a trait?
Different genotypes can result in the same phenotype through mechanisms such as genetic redundancy or epistasis. Genetic redundancy occurs when multiple genotypes can produce the same gene product, leading to the same phenotype. Epistasis occurs when one gene's expression is influenced by another gene, allowing different genotypes to result in the same observable trait.
How cant two plants that have different genotypes have the same phenotype?
They cannot
Can two horses have the same phenotype but different genotypes?
Yes, it is possible for two horses to have the same phenotype but different genotypes. Phenotype is the observable characteristics of an organism, while genotype refers to the genetic makeup. Differences in genotype can lead to variations in the genetic composition that may not be visibly apparent in the phenotype.
How can you have the same phenotype but different genotype?
Different genotypes don't always change your phenotypes because of mutations
How can two plants have different genotypes having the same phenotype?
The simplest way that two plants can have different genotypes, but the same phenotype, is if they both have a dominant allele for the same trait. For example, the genotypes Pp and PP, will both produce the phenotype created by P (for example, pink coloured petals). This is because P is dominant to p, and will always be expressed. Other ways that the same phenotype can be created from different genotypes are when the environment affects the traits, or when the trait is controlled by more than one gene.
Describes organisms or genotypes that are homozygous for a specific trait and thus always produce offspring that have the same phenotype for that trait?
True-breeding
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.
How is it possible for individuals to have the same phenotype but different genotypes for a trait?
it is possible beccause you dont always need both
What is a true - breeding plant?
True-breeding is an organisms or genotypes that are homozygous for a specific trait and thus always produce offspring that have the same phenotype for that trait.
What describes organisms or genotypes that are homozygous for a specific trait that always produce offspring of the same phenotype?
Organisms or genotypes that are homozygous for a specific trait and always produce offspring of the same phenotype are said to be true breeding. This means that when bred with another organism of the same genotype for that trait, all offspring will display the same characteristic.
Which statement describes how two organisms may show the same trait yet have different genotypes for that phenotype?
Organisms that share genotypes share the same alleles, whereas organisms that share phenotypes share expressed traits. Sometimes multiple genes code for the same phenotype, and the classical study used to illustrate this (or at least one of them) is on Mendel's experiments on plants.Simply put, Mendel's work helped demonstrate how dominant and recessive alleles affect phenotype. When an allele is completely dominant, an organism will display the dominant phenotype whether or not it has one or two dominant alleles (assuming the alleles share the same locus). So for instance two different pea plants (this example is made up to display the concept) may have two different genotypes, one with two dominant alleles and one with a single dominant and single recessive allele; these organisms have different genotypes. However, because the dominant allele is completely dominant, both would organisms would express the same phenotype.A perhaps more eloquent explanation of the above example exists at the Mendelian inheritance article on Wikipedia.
