This means that the tall pea plant had a double dominant height gene (each gene has 2 parts, one from each "parent"). The short pea plant had a double recessive gene making it short. When the two plants bread, the dominant gene always is the one that shows up, so the plant was tall.
Tt and TT were the genotypes of the true breeding plants that Mendel used in his two factor cross.
Mendel crossed true-breeding pea plants with contrasting traits in his first generation experiments. Specifically, he crossed a true-breeding purple-flowered plant with a true-breeding white-flowered plant.
When Mendel crossed true-breeding pea plants with different traits, he observed that the offspring in the first generation (F1) all displayed one of the parental traits. This led him to propose the Law of Dominance, which states that one trait will mask or dominate another in hybrids.
When two true-breeding plants are crossed, the offspring will inherit one allele from each parent for a specific trait. Since both parents are true breeding, all offspring in the first generation (F1) will exhibit the dominant trait, assuming the traits are determined by simple dominance. If the F1 generation is then self-crossed, the resulting F2 generation will display a phenotypic ratio that reflects the segregation of alleles, typically following Mendel's laws of inheritance.
The original generation for pea plants in Mendel's experiment is called the P generation, or parental generation. This generation consisted of the true-breeding plants that Mendel used to establish the traits he studied. The P generation was crossed to produce the F1 generation, which exhibited the traits inherited from the P generation.
he used plants that were NOT true breeding!
because it helped Mendel discover which plants would be crossed to produce offspring.

Gregor Mendel's theories are the basis for modern breeding techniques of plants and animals. Mendel was a German friar who experimented with breeding pea plants.
When Mendel crossed a true-breeding short plant with a true-breeding tall plant, all the offspring were tall. Which term describes the gene for tallness?

purple is dominant over white in Mendel's pea plant experiment, meaning that the offspring inherited at least one purple allele from the purple parent. This resulted in all the offspring showing the purple trait.
All the offspring were purple because Mendel was dealing with simple genetic dominance. The purple true breeding parent was homozygous dominant and the true breeding white parent was homozygous recessive. When those two are crossed they create only heterozygous offspring (look up a punnett) and since this is simple dominance those heterozygous will show the phenotype of the dominant allele which is purple.
