How can you determine the genotype of a plant that displays the dominant for a tra how can you determine the genotype of a plant that displays the dominant form of a 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.
