Tt is a genotype. Each letter is called an allele and represents a different trait. For instance, the T could stand for tall, and the t could stand for short. Because the T is a capital letter, it is the dominant trait. In the case of Tt, the person would be tall. If the genotype was TT, the person would again be tall. If the genotype was tt, the person would be short. All traits are represented by two or more alleles. Things like blood type are represented by multiple alleles.
Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.
The allele pair of someone with a genotype TT is homozygous dominant.
Tall = T short = t Tall plants genotype would either be TT or Tt, and short plants genotype would be tt.
Because the shot gene in the pea plant is a recessive trait, there is only one possible genotype for it: tt
The allele pair of someone with a genotype TT is homozygous dominant.

A tall looking pea plant can have a genotype of Tt or TT.
A heterozygous genotype
Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.
two capital or two lowercase letters in the GENOTYPE (ex: TT or tt) it's also called HOMOZYGOUS.
The allele pair of someone with a genotype TT is homozygous dominant.
The allele pair of someone with a genotype TT is homozygous dominant.
Tall = T short = t Tall plants genotype would either be TT or Tt, and short plants genotype would be tt.
genotype of the parents - parents will be heterozygous dominant. e.g. take the example of Mendel's pea cross. if parent is heterozygous dominant then the genotype will be Tt and Tt now if you will do a cross then the result you will get is this - Tt X Tt result - TT, Tt, Tt, tt it gives a 3 : 1 ratio i.e. three tall and one dwarf.
