Which letter can be used to model Mendels cross of true-breeding tall plants with true -breeding short plants in a Punnett square?
True breeding tall plants would be TT and true breeding short plants would be tt, so TT x tt would illustrate the crossbreeding.

Why is it important that Mendel began with purebred plant?
The correct term is "true-breeding". What that means is that if he takes his two pea plants with white flowers and breeds them together, he will always get a pea plant with white flowers. Something that is true-breeding for a particular trait is homozygous, i.e. if the allele for red flowers is R and the allele for white flowers is w, then a true-breeding white flowering plant is ww, and true-breeding red flowering plant is RR. If you cross-breed a true-breeding red flowering with a true-breeding white flowering plant, you would get 1/4 of the offspring as true-breeding red flowers, 1/4 of the off-spring as true-breeding white flowers, and 1/2 the offspring as heterozygous (not true-breeding) red flowers - Rw. If you don't start with true-breeding plants - say you start with Rw and ww (a red and a white plant) you get 1/2 the offspring heterozygous red, and 1/2 true-breeding white. Thus if you didn't know anymore, you would assume that half the time when you breed a red and a white plant, you would get a red plant, and half the time a white, which is incorrect. Furthermore, if you conducted the experiment again, say with RR and Rw, you would get a different result (in this case, all red). By starting with plants that are true-breeding, you ensure that you get the same results that properly show how the traits are passed on.
How Mendel's experiments would have been different if hr had not worked with true breeding plant?
If Mendel's experiments were not true breeding, then he would not be ablt to tell the recessive alleles showed up in the F2 progeny. Since the F1 generation would have showed the dominant trait regardless, the only way to show the recessive alleles carry to the F2 is to have true breeding parents.
What is the percentage of Polydactyl Cats?
Polydactyl is a genetic abnormality that is sometimes seen in cats as well as other species. Polydactyl cats are not bred to have the extra digits, and there is no true percentage of this occurrence. The only exception is the Maine Coon which disreputable breeders will attempt breeding.
Could you establish a true breeding variety of pink snapdragons?
no, u cannot. you have to have a parent with the red gene and a parent with the white gene, which would be heterozygous (different). and true breeding is homozygous.
what do true breeding pea plants always produce?
A specific trait. There are true-breeding tall pea plants and true-breeding short pea plants, etc... .
If Gregor Mendel didn't use plants that were not true breeding then would he have discovered dominant and recessive traits?
If Gregor Mendel did not use plants that were not true breeding, he would not have discovered heredity because there would not be any evidence that traits passed on to the next generation and that the offspring retained the traits of the parents.
What is the genotype of a pea plant that is true-breeding for purple flowers?
The answer is all of the produced flowers would be Pp
