What did mendel perform when he crossed plants that were heterozygous for two traits?
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?
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?
Dominant.
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
The best definition of a true-breeding plant is one that?
self-fertilizes to produce offspring identical to the parent
What does it mean for a pea plant to be true breeding?
all offspring in every generation will have the same characteristics of parent plants

Dominant.
What plant produces offspring's with the same trait as the parents?
answer: true breeding plant
What is the meaning of true-breeding plant?
A true breeding plant is genetically homozygous. It produces the same type of plants on self fertilization. These plants are very useful for creating hybrids.
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.
What is a true - breeding plant?
True-breeding is an organisms or genotypes that are homozygous for a specific trait and thus always produce offspring that have the same phenotype for that trait.
