For example, if the tall plant stand for T, the genotypes are:
TT
tt
The genotype of a heterozygous tall plant would be Tt, with one allele for tallness (T) and one allele for shortness (t).
Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.
The word genotypes is in reference to the alleles an individual receives at fertilization. Lets say that the allele/gene/trait, genotype for the Tall plant is T and dominate and the allele/gene/trait genotype for the short plant is t and recessive. If the genotype is an homozygous allele/gene/trait has two dominate alleles/genes/traits seen as two capital letters ex: dominate tall=TT or if the genotype is homozygous with two recessive alleles/genes/traits it will have two lower case letters ex: short=tt. If the genotype is heterozygous is a Tall plant that means the allele/gene/trait will have one dominate T=Tall and one recessive t=short and it will look like this Tt and with this genotype a Tall plant will be produce "T", even though that plant will still carry an allele/gene/trait for shortness "t". Tips: homozygous [Gk.homo means same and zygous means balance] & heterozygous [Gk.hetero means different and zygous means balance]
Tt
What is the genotype and phenotype of the F1 generation
homozygous- TT; heterozygous- Tt :)
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
The tall tea plant could either be homozygous dominant (TT) or heterozygous (Tt) for the tall trait. Since a test cross involves crossing the tall plant with a homozygous recessive plant (tt), and produces only tall offspring, this indicates that the tall plant must be homozygous dominant (TT). Thus, the genotype of the tall tea plant is TT.
The genotype of a heterozygous tall plant would be Tt, with one allele for tallness (T) and one allele for shortness (t).
A. homozygous at two loci (AA & cc).

Do a testcross with a homozygous recessive plant.
Do a testcross with a homozygous recessive plant.
Are you talking about phenotype or genotype? Phenotype is the expression of the genotype. Genotype is what you inherited. Phenotype is what you see. Homozygous is the same. Heterozygous is different. If you inherit one allele for blue eyes and one allele for brown eyes, your phenotype should be brown eyes. Your genotype would be brown eyes, blue eyes. You would have a heterozygous genotype.

Do a testcross with a homozygous recessive plant.
