Why did mendel use garden peas in his garden?
Mendel chose peas because they had seven traits that he could study. Peas are easy to grow and they self fertilize.
What organism did mendel use for this study on genetics?
Mendel studied pea plants. He chose strains that bred true for traits like pea color, flower color, and height. By crossing plants that bred true for these traits he was able to determine that offspring were not a "blend" of their parents and that traits were passed on by what we now know as genes in patterns that could be predicted from one generation to the next.
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 didn't Mendel observe linkage?
Mendel did not observe linkage because, by chance, he chose traits whose genes resided on different chromosomes. Genes on different chromosomes assort independently. To answer the question of 'Who discovered gene linkage?'...The answer is British geneticists William Bateson and Reginald Punnett.
Why did Mendel test one trait at a time?
Mendel tested one trait at a time so he would be able to eliminate variables. The purpose of his experiment in general was to determine the trends and patterns in inheritance, and so he had be sure he studying only one variable at a time, to understand it well. Specifically, he examined one trait at a time with self-pollinating pea plants, of which there were only two color varieties: purple and white. Before now, there was no chance of white flower's seed having previously been fertilized by a purple flower. He also chose to use peas because they spawn a new generation quickly and produce a large number of offspring. So during the first generation of his pure purple flower and pure white flower crossing, all of the offspring produced purple flowers. Because his subjects were chosen only for the reason of color, and did not differ in other ways, he knew, what would later become known as, the purple-color allele was dominant. It was previously believed that the two colors would "blend" together, producing a pale purple color. So it would make sense that the trait for producing a white flower was lost, and that the flowers would be purple from now on, right? When the this generation self-fertilized, however, there was 3:1 ratio of offspring. 3 purple flowers and 1 white flower. Mendel now had a basis for determining the law of segregation. Later, after performing other various two-option-single-trait experiments such as seed color and wrinkled vs. smooth, he discovered traits were inherited singly, and thus the law of independent assortment was born. Mendel's experiments gave in beautifully to ratios of inherited traits and the ability to determine what traits the offspring would possess as more traits were mixed. If he had tested multiple traits at one time, even unintentionally, his results could have been skewed and even meaningless.
What was the main experiments Gregor Mendel carried out?
In mendels first experiments, he crossed pea plants to study seven different characteristics. For example he crossed plants that had purple flowers with plants that had whit flowers, the offsprings from such a cross are called first- generation plants. All of his first generation plants had purple flowers. One trait was always present in the first generation , and the other trait seemed to disappear. Mendel chose to call the trait that appeared the dominant trait. Because the other trait seemed to fade into the background, Mendel called it recessive trait.
Why did Mendel use pea plants in his experiments?
They Self-fertilize. -Apex
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.

Mendel chose peas because they had seven traits that he could study. Peas are easy to grow and they self fertilize.
Why gregor mendel choose pea plants for his experiment?
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 organisms did Gregor Mendel decide to use to study trait patterns and why?
Pea plants. Specifically, Pisum savitum . Although Mendel never SPECIFICALLY stated why he chose this species to do his tests, it does has several advantages for the experiments he wanted to do:1) It has several traits that are easy to identify.2) Seven of these traits are independent of each other. We now know that many genetic traits of DNA life-forms are inter-linked, such that breeding two plants with one type of trait difference results in differences in other traits.3) It's easy to breed peas with different traits amongst each other.4) It produces offspring rapidly.
