A heterozygous genotype
For example, if the tall plant stand for T, the genotypes are: TT tt
false
Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.
A tall looking pea plant can have a genotype of Tt or TT.
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.
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 is the allele combination and phenotype is the physical appearance of the result of the genotype. Genotype for tallness may be: Tt Phenotype example: Brown hair, blue eyes, widow's peak, etc.
A phenotype is a physical characteristic of an organism, such as a tall pea plant. An organism's genotype is the specific gene combination that makes up a characteristic using Punnett Square. For example, a tall pea plant might have a genotype of TT or Tt, whereas a small pea plant may have a genotype of tt. (Note: In this case "T" is dominant and "t" is recessive.)
