Mendel used all tall plants in his F1 experiment because that was the offspring from his cross of a pure tall plant and a pure short plant. By crossing two of the tall plants from F1, he proved that the recessive gene (t) was still present in the F1 generation, despite the phenotypes of all of these plants being tall. (The result of the F1 cross gave 3 tall plants and 1 short plant.)
What else can I help you with?
When Gregor Mendel crossed purebred short plants with purebred tall plants all of the offspring were?
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.
What happened when Mendel crossed purebread tall tea plants with purebread short tea plants?
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.
When gregor mendel crossed true bleeding tall plants with true bleeding short plants plants all the offspring were tall because?
When Gregor Mendel crossed true-breeding tall plants with true-breeding short plants, all the offspring were tall because the tall trait is dominant over the short trait. In this cross, the tall plants contributed a dominant allele, while the short plants contributed a recessive allele. Since the presence of just one dominant allele is sufficient to express the tall phenotype, all the F1 offspring exhibited the tall trait. This foundational experiment established key principles of inheritance.
What observations led Mendel to conclude that some traits were recessive?
Mendel selected true breeding tall (TT) and dwarf (tt) pea plants. Then, he crossed these two plants. The seeds formed after fertilization were grown and these plants that were formed represent the first filial or F1 generation. All the F1 plants obtained were tall.Then, Mendel self-pollinated the F1 plants and observed that all plants obtained in the F2 generation were not tall. Instead, one-fourth of the F2 plants were short.From this experiment, Mendel concluded that the F1 tall plants were not true breeding. They were carrying traits of both short height and tall height. They appeared tall only because the tall trait is dominant over the dwarf trait.
Why were all of the F1 plants of Mendel's peas were tall?
All of the F1 plants of Mendel's peas were tall because the tall trait was dominant over the short trait. Mendel crossed purebred tall peas (TT) with purebred short peas (tt), resulting in F1 offspring that all inherited one tall allele from each parent (Tt). Since the presence of just one dominant allele (T) is enough to express the tall phenotype, all F1 plants exhibited the tall trait.

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.

What were gregor Mendel's experiment's?
i believe his results were that after cross pollinating to non-purebred pea plants, the offspring were all tall like the female,and when he crossed the other two, he received three tall pea plants and one short

In which generation were recessive traits hidden in all the plants in Mendel's experiment?
f2 generation

What is Mendel's experiment?
Gregor Mendel developed the model of heredity that now bears his name by experiments on various charactersitics of pea plants: height (tall vs. Short); seed color (yellow vs. Green); seat coat (smooth vs. wrinkled), etc
When Gregor Mendel crossed a tall plant with a short plant what where the results of the F1 generation?
The F1 generation of crossing a tall plant with a short plant resulted in all tall plants. This is because the tall trait is dominant and the short trait is recessive in Mendel's experiments with pea plants.
Why were all of mendels first generation plants tall?
All of Mendel's first-generation plants were tall because they were all homozygous dominant for the trait of tallness. This means they received two dominant alleles for tallness from the parental plants, resulting in expression of the tall phenotype.
When Mendel crossed purebred short plants with purebred tall plants all of the offspring were?
I think not as tall is the dominant allele here.T = tallt = shortTT X ttall would beTt======and tall.
What explains Mendel's observations that all first generation pea plant were tall?
Mendel's observations that all first-generation pea plants were tall can be explained by the dominance of the tall allele over the short allele in his experiments. He performed hybridizations between true-breeding tall and short pea plants, where the tall trait was dominant. As a result, all offspring in the first generation (F1) exhibited the dominant tall phenotype, masking the expression of the recessive short phenotype. This pattern laid the foundation for Mendel's laws of inheritance.
