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.

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.


In which generation were ressesive traits hidden in all the plants in mendels experiments?

If you made a Punnett square showing Gregor Mendels cross between true breeding short plsntd the square would show that the offspring had what?

The Punnett square would show that all offspring would be heterozygous for the trait, meaning they would have one allele for tall plants and one allele for short plants. This would result in all offspring being tall plants phenotypically, but carrying the allele for short plants.


Are all tall peas always purebred for tallness?

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 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.

If tall peas are crossed with dwarf peas what percent of the peas will be tall in the first generation?

In the first generation of crossing tall peas with dwarf peas, all the offspring will be tall. This is because the tall trait is dominant over the dwarf trait. Each offspring will inherit one tall allele from the tall parent, resulting in all tall offspring.

What is the basis for law?

Mendel first described what is called genetics. He used sweet peas and crossed pure bred plants. For example, he crossed short pure bred (recessive) with tall pure bred plants (dominant). If tall is dominant, all plants would be tall. Crossing these hybrid plants would give a ratio of 3 tall to 1 short. This is the basis from which all studies of genes come from.
