Cross Pollination
All the offspring were tall plants. This is because the tall trait is dominant over the short trait in Mendel's experiments on pea plants.
Gregor Mendel took two different colored pea plants: one had traits for white plants and the other had traits for a red plant. When Mendel cross bred the two plants, a plant with traits for a pink plant grew. This is how Mendel contributed to the understanding of inherited traits.
I think not as tall is the dominant allele here.T = tallt = shortTT X ttall would beTt======and tall.
No, not all tall pea plants are purebred for tallness. In Mendel's experiments with pea plants, tallness is a dominant trait, but if a tall plant is heterozygous (having one allele for tallness and one for shortness), it can produce offspring that are either tall or short. Only plants that are homozygous for the tall trait (having two alleles for tallness) will consistently produce tall offspring. Thus, genetic testing or breeding records are needed to determine if a tall pea plant is purebred.

When Mendel crossed purebred tall tea plants with purebred short tea plants, all the offspring in the first generation (F1) exhibited the tall phenotype. This outcome demonstrated the concept of dominance, where the tall trait masked the short trait. When Mendel allowed these F1 plants to self-pollinate, the second generation (F2) revealed a 3:1 ratio of tall to short plants, indicating that the short trait was still present as a recessive trait. This experiment laid the foundation for Mendel's laws of inheritance.
Mendel used purebred plants to ensure that the offspring of his experiments would have consistent and predictable traits. By controlling the genetic makeup of the parent plants, he could more easily observe and analyze the patterns of inheritance in their offspring.
In his first set of experiments, Mendel crossed purebred pea plants with different traits, such as tall and short plants. He observed the inheritance patterns in the offspring of these crosses over several generations. Mendel showed that traits are inherited independently and proposed the laws of segregation and independent assortment.

In Mendel's experiments, recessive traits were hidden in the F1 generation, which consisted of the offspring resulting from the cross of two purebred parent plants with contrasting traits. These F1 plants exhibited only the dominant traits, while the recessive traits were not expressed. However, when the F1 plants were self-pollinated to produce the F2 generation, the recessive traits reappeared in a predictable ratio alongside the dominant traits.
Mendel obtained his P generation by cross-breeding selected purebred plants that displayed contrasting traits. This allowed him to study how traits are passed down from one generation to the next.
