The phenotype Tt refers to an organism with one dominant allele (T) and one recessive allele (t) for a specific trait. The dominant allele typically determines the observable characteristics, so the phenotype will reflect the traits associated with the dominant allele. For example, if T represents tall stature in plants and t represents short stature, the Tt organism would exhibit the tall phenotype.
An organism's allele pairs, such as TT, tt, or Tt, represent its genotype. The genotype refers to the specific genetic makeup of an organism, including the alleles it carries. In contrast, phenotype refers to the observable traits or characteristics that result from the interaction of the genotype with the environment.
The ratio produced if Tt is crossed with tt is 1:1 for the genotype and 1:1 for the phenotype. This is because all the offspring will inherit a recessive allele from the tt parent, resulting in all of them having the same genotype and phenotype.
The genotypes TT and Tt represent different combinations of alleles for a particular gene. TT is homozygous dominant, meaning it has two identical dominant alleles, while Tt is heterozygous, containing one dominant allele (T) and one recessive allele (t). This difference can affect the expression of traits, with TT typically exhibiting the dominant phenotype and Tt also showing the dominant phenotype, but potentially carrying the recessive trait.

The phenotypic ratio for the given genotypes (TT, Tt, TT, Tt) can be determined by identifying the traits represented by these genotypes. In this case, both TT and Tt result in the dominant phenotype, while there are no recessive phenotypes present. Thus, the phenotypic ratio is 4:0, indicating that all offspring display the dominant trait.
Nope! TT is the dominant phenotype (what ever it may be) and tt is the recessive phenotype (what ever that may be).So say T is the allele for Tall plants, t is the allele for short plants. TT would be show the tall phenotype while tt would show the short phenotype. If the genotype was Tt, the phenotype would be tall as well because the T is dominant and masks the phenotype of t (short plants).
Codiminant principle suggests that a plant with the genotype Tt will display a tall phenotype.
Codiminant principle suggests that a plant with the genotype Tt will display a tall phenotype.
An organism with two genes or alleles, such as TT or tt, is said to be homozygous for a particular trait. In this case, TT represents a homozygous dominant genotype, while tt represents a homozygous recessive genotype. These genotypes can influence the organism's phenotype, or observable characteristics, depending on the dominance of the alleles involved. For example, if T is dominant over t, the phenotype of TT and Tt would be the same, while tt would have a different phenotype.

Tt X Tt Statistically, 1 TT Homozygous dominant, expresses T. 2 Tt Heterozygous dominant, expresses T. 1 tt Homozygous recessive, expresses t.
OK first, you don't say tT. The dominant allele is always put first. So this would actually be TT Tt Tt and tt. The only way a recessive trait will show is if the dominant trait isn't present. Therefore 3 will be tall and one will be short. BTW: TT isn't an example of an allele. It's actually the genotype. T is an example of an allele. Tallness is a genetic trait, but T is not. A genetic trait is simply a title that includes whatever phenotype may become apparent. A phenotype is the trait that shows up. If a person's genotype is TT or Tt, their phenotype will be tall. If a person's genotype is tt, then their phenotype will be short.
The ratio produced if Tt is crossed with tt is 1:1 for the genotype and 1:1 for the phenotype. This is because all the offspring will inherit a recessive allele from the tt parent, resulting in all of them having the same genotype and phenotype.
