Dominant alleles are expressed, even if a recessive allele is also present. In the notation used, a capital letter means a dominant allele - therefore the presence of a P (in either PP or Pp) means the organism will display the trait P creates.

Can two organisms have different genotypes but the same phenotype?

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....


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.


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.


Name two factors that determine the phenotype of a trait?

genes


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.

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.


Are phenotype and genotype traits the same?

No, phenotype refers to the physical traits or characteristics that are observable in an organism, while genotype refers to the genetic makeup of an organism, including both the genes that are expressed and those that are not. So, while genotype influences phenotype, they are not the same thing.


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.

Can you have the same genotype but different phenotype?

yes


What is the difference between genotype and phenotype and give examples?

A genotype is the actual genetic coding for an organism A phenotype is the physical appearance For example, let's say BB or Bb is the coding for black hair. BB/Bb is the genotype, and the black hair is the phenotype


How are genotype and phenotype alike?

Genotype is the specific combination of genes that contribute to a trait that an organism has. (For example, the genes for being tall).Phenotype is the expression of the trait which is partially influenced due to the genotype and partly by the environment (Even if you have the genes for being tall, if you are malnourished you will not grow as tall).


What was the genotype of the offspring that did not share the parent's phenotype?

The genotype of the offspring that had the same phenotype as the parents is rr or wrinkled. The phenotype for the seed shape of both parent plants is round.


When genetics refer to the physical characteristics of an organism they are talking about its what?

Phenotype. The physical expressed characteristics of an organisms genotype is known as its phenotype. Two organisms may have the same phenotype, but different genotype depending on the dominate or recessive genes present. Just remember physical=pheno.


How are an individual's genotype and phenotype different?

The genotype of an organism is the group of characteristics derived from a combination of heredity and environmental factors. Genotype is based on genetic factors only. phenotypes are the genes that an organism carries. For example, the gene for blue eyes could be b and the gene for brown eyes could be B. Bb is a genotype. Phenotype is the trait that show up. Since brown eyes are dominant, the phenotype of Bb would be brown eyes.


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.


The Phenotype determines genotype?

Phenotype does not determine genotype. Actually a genotype includes an organisms entire hereditary information. A phenotype is simply the organisms actual observed properties including appearance, development and behavior.
