Because the Tall gene in plants is dominant, a plant that has the genotype Tt (Heterozygous) would be a Tall plant.
Because the Tall gene in plants is dominant, a plant that has the genotype Tt (Heterozygous) would be a Tall plant.
Three types of genotypes that exist for pea plant height are: TT - Homozygous dominant genotype for tall height Tt - Heterozygous genotype for tall height tt - Homozygous recessive genotype for short height
Tall = T short = t Tall plants genotype would either be TT or Tt, and short plants genotype would be tt.
A tall looking pea plant can have a genotype of Tt or TT.
false
In pea plants, the trait for tallness is typically dominant, while the trait for shortness is recessive. In a case of simple dominance, a plant with a genotype that includes at least one dominant allele for tallness (e.g., TT or Tt) will be tall. Conversely, only a plant with the homozygous recessive genotype (tt) will be short. Thus, a plant with the genotype TT or Tt will be tall.
For example, if the tall plant stand for T, the genotypes are: TT tt
The plants will all express the dominant gene.
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).
if we assume tall plant <T> & short plant as< t> genotype of tall plant ; TT genotype of short plant ; tt
Codiminant principle suggests that a plant with the genotype Tt will display a tall phenotype.
Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.
