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 information was Mendel known before he started his experiment?
Before starting his experiments, Gregor Mendel was aware of the existing theories of inheritance and the work of other scientists on hybridization and plant breeding. He understood that traits were passed from parents to offspring but lacked a clear mechanism explaining how this occurred. Mendel was also influenced by the work of botanists and scientists who studied pea plants, which ultimately led him to choose them for his experiments due to their clear traits and ease of cultivation. His background in mathematics also helped him apply statistical analysis to his findings.
Why did mendel choose that type of plant?
Mendel chose the pea plant (Pisum sativum) for his experiments due to its distinct and easily observable traits, such as flower color and seed shape. Pea plants also have a relatively short generation time, allowing for quick observation of inheritance patterns across multiple generations. Additionally, they can self-pollinate or be cross-pollinated, giving Mendel control over their breeding and facilitating his studies on heredity.
Why did Mandel choose peas for his experiment?
Mendel chose peas for his experiments because they are easy to grow, produce a large number of offspring, have distinct characteristics that can be easily observed and manipulated, and can self-pollinate or cross-pollinate with other pea plants. These features allowed Mendel to carefully control the breeding process and make accurate observations about inheritance patterns.
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.

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.
Why did Mandel choose peas for his experiment?
Mendel chose peas for his experiments because they are easy to grow, produce a large number of offspring, have distinct characteristics that can be easily observed and manipulated, and can self-pollinate or cross-pollinate with other pea plants. These features allowed Mendel to carefully control the breeding process and make accurate observations about inheritance patterns.
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.

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.
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?
Pea plants are easy to cultivate and have a short life cycle, allowing for quick observations and experiments. Pea plants have distinct traits that are easy to observe and manipulate, such as seed shape, color, and height. Pea plants can self-fertilize or be cross-fertilized, providing opportunities to study inheritance patterns. Mendel could control the crosses of pea plants to carefully track the transmission of traits from one generation to the next.
