two capital or two lowercase letters in the GENOTYPE (ex: TT or tt) it's also called HOMOZYGOUS.
Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.
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.

A tall looking pea plant can have a genotype of Tt or TT.
Because the shot gene in the pea plant is a recessive trait, there is only one possible genotype for it: tt
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).
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.
Total dominant genes or total recessive genes. Therefore, either TT or tt, not Tt.
Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.
