For example, if the tall plant stand for T, the genotypes are:
TT
tt
If the letter T represents the dominant allele for tall stems in pea plants, the genotype that has two tall alleles is homozygous dominant, and is written TT.
No. A hybrid is heterozygous, and a pea plant that is a hybrid for stem length would have the heterozygous genotype Tt.
TT and Tt
DD is homozygous dominant is a genotype which gives tall plant.
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]
Homozygous dominant would be all Capital letters. Homozygous recessive would be all lower case letters. So...in basic color genetics for horses: A homozygous recessive horse would be aaee A homozygous dominant horse would be AAEE
What is the genotype and phenotype of the F1 generation
homozygous- TT; heterozygous- Tt :)
DD is homozygous dominant is a genotype which gives tall plant.
A. homozygous at two loci (AA & cc).
Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.

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.
