Do a testcross with a homozygous recessive plant.
To determine the genotype of a plant displaying a dominant trait, perform a test cross by breeding it with a homozygous recessive plant for that trait. If any offspring display the recessive trait, the dominant plant is heterozygous; if all offspring show the dominant trait, the plant is likely homozygous dominant. Analyzing the offspring's phenotypes will provide insight into the genotype of the parent with the dominant trait.
To determine the genotype of a plant displaying the dominant form of a trait, you can perform a test cross by breeding it with a homozygous recessive plant for that trait. If any offspring display the recessive phenotype, the dominant plant is heterozygous; if all offspring show the dominant phenotype, the plant is likely homozygous dominant. This method allows you to infer the genotype based on the phenotypic ratios observed in the offspring.

Identify the genotype trait of the seed color is yellow or green?
Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.
The genotype of a pea plant with two alleles YY is homozygous dominant. This means that both alleles for the trait in question are the same and dominant. In this case, the plant will express the dominant trait associated with the YY genotype.
