Why did Gregor Mendel choose to use purebred plants in his experiments?

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.

∙ 8y agoPea plants are self-fertile so it is easy to obtain parent plants that "bred true." That is when allowed to self-fertilize, the offspring always had the same appearance as the parent plant. By starting with pure strains for each trait such as tall or dwarf, the offspring would indicate which trait is dominant. If a tall plant is crossed with a dwarf plant, all the offspring are tall. Therefore the gene for tall is dominant to the trait for dwarf but the tall offspring are also carrying a gene for dwarfism.

∙ 9y agoIt was easiest since he was a monk. It didn't cost much and added to the table. He was very lucky since the plants he used had such simple traits.
The characters were fixed (stablized) in purebred plants hence it was easy to study their inheritance pattern.

Why did Gregor Mendel use pea plants?
Gregor Mendel chose the pea plants for his experiments because the garden pea is an ideal subject in the study of genetics for the following reasons:-- presence of observable traits with contrasting forms-- produces many offspring in one cross-- short life cycle-- ease in manipulating pollination (cross pollination)Pea plants had the following chacracteristics:plants were sexually reproducing with bisexual flowersself pollination and self fertilization is possiblethe life cycle was completed in one seasonhybrids were perfectly fertilemany varieties with well-defined characters were available i.e. presence of seven pairs of contrasting or allelomorphic charactersPea plants (leguminosae) have an irregular flower in which the top part of the corolla is much larger than the lower part (Hitchcock and CronquistFlora of the Pacific Northwest p228). If you haven't ever seen a pea flower, it looks much like a snap dragon bloom. This feature keeps the flowers from freely pollinating each other by wind, as they are tightly shut. If protected from pollinating insects, they will only self pollinate, or if the anthers are clipped off they can be very selectively pollinated by a person. This gave Mendel much tighter control over the crossbreeding of the plants.Because pea plants are easy to propagate and have 7 observable traits like Seed Shape, seed color, Seed coat color, pod shape, flower position and stem lengthThis can be speculated, but pea plants were probably picked because of their ability to reproduce quickly. If Gregor Mendel had used an animal, he would have had to wait many years before being able to study the passing on of traits.He chose them because they are quick and easy to grow and several peas are produced in each pod. It is fortunate that he chose the plant that he did, and that he chose the characteristics he did to observe. Some plants would have been much more difficult to work with.

What would maggots do in a choice chamber?
If they have a choice of wet or dry they will choose wet and if it was light or dark they will choose dark.
Why did Mendel choose the garden pea plant as his experimental organism?
He studied plants and was a gardener.
Why Mendel choose gardenpea in his experiment?
mendel worked in a monastery that was already studying garden peas. because they were readily available to him he experimented with them
Varieties of purebred dogs are maintain by?
Professional breeder's who choose only the best lines.
What plant did Mendel study to learn the basic mechanisms of heredity?
Mendel choose the garden pea because the garden peas have a number of characteristics that are expressed in one of ways.
Which of the following was Mendel's experimental organism?
Please resubmit your question with more information: what "following" do you what us to choose from.
Why mendel choose pea plant give reason in points?
the peas pland easily grow. they easily reprodunce.
What do you breed a light bay with to get an Appaloosa on Howrse?
An Appaloosa although you may get the breed of the light bay. You can't choose the coat or gender of the foal. And unless it's purebred you can't choose the breed either.
Why do most translators of Kafka's The Metamorphosis choose to use the term vermin instead of cockroach?
The answer is B Vermin is less specific, so the reader feels as confused as Gregor about what is happening.
Why gregor mandel choose garden pea?
One of the reasons that Mendel carried out his breeding experiments with pea plants was that he could observe inheritance patterns in up to two generations a year.AnswerBecause he did a lot of research and found that peas most readily demonstrated the genetic factors he wished to show.

Why should Mendel choose to study pea plants to learn about inheritance?
He chose peas because they grow easily and quickly, and it's easy to see and recognize their different traits.
