★★★ Correct answer to the question: Gregor Mendel observed that pea plant traits did not blend in their offspring. Gregor Mendel chose pea plants for his experiments because they are easy to raise, have many offspring per mating, can fertilize themselves and have varieties in genotype and phenotype that are easily observable. […] Gregor Mendel DRAFT. Why did Mendel use a pea plant in his experiments 2 See answers robert7248 robert7248 In approximately 29,000 pea plants, Gregor Mendel carried out hybridization experiments. When Mendel first began his work with pea plants, the scientific concept of heredity was rooted in the concept of blended inheritance, which held that parental traits were somehow mixed into offspring in the manner of different-colored paints, producing a result that was not quite the mother and not quite the father every time, but that clearly resembled both. Gregor Mendel was an Austrian monk who discovered the basic principles of heredity through experiments in his garden. It was not by accident that it became his experimental plant. (viii) Contrasting characteristics, such as tall-short, etc occurs a pea plant. (ii)They have a short life-cycle. Self-pollination occurs easily since the plant is bisexual. He was born on July 22, 1822, and it is said that from an early age he was in direct contact with nature, a situation that made him interested in botany. 69% average accuracy. As the time gap between generations was short, Mendel could raise many generations of a pea within a short time. Thus, many generations of this plant can be examined in a very short span of time. He measured seven pea characteristics: Color and smoothness of the seeds - grey and round or white and wrinkled It was usually self-fertilizing (self-pollinating) that is the fertilization of plants and some invertebrate animals by their own pollen or sperm rather than that of another individual, but could also be cross-fertilized (cross-pollinated) that is the transfer of pollen grains from an anther of a flower of one plant to a stigma of a flower of another plant of the similar species. C. They are easy to grow. Mendel carried out his key experiments using the garden pea, Pisum sativum, as a model system. Pea Plants. smooth seed coats) clearly evident in archaeological sites that date back to 6500 BC. © copyright 2020 QS Study. Modern genetics begins with the work of, That the inheritance of each trait is determined by "units" or "factors" (now called genes) that are passed on to descendents unchanged, That an individual inherits one such unit from each parent for each trait. (v) Big flower of pea plant makes pollination easier. Between 1856 and 1863 Mendel cultivated and tested some 29,000 pea plants (i.e., Pisum sativum). Gregor Mendel wondered why different pea plants had: * 1) Many parents 2) So much pollen 3) Different characteritics 4) None of the above His "control" was trying to always match the 3:1 ratio. The Gregor Johann Mendel Experiment. Gregor Mendel used the common garden pea in his experiments the results of which became the basis of the science of genetics. For example, he tended at least 50 hives of bees, he reported his weather for the Austrian Empire, and his fellow monks elected him as the abbot to this monastery. These characteristics make pea plants ideal in the study of genetics and heredity. Get an answer to your question "Why did Gregor Mendel study pea plants?a. (ix) The life span of a pea plant is short, thus many generations can be obtained in a single growing season. b. Even from the start, he was already aware that the right experimental plants must be used in order to avoid the “risk of questionable results”. Gregor Mendel chose pea plant because the garden pea is an ideal subject in the study of genetics for the following reasons: (i)They grow quickly. He picked out the pea plant due to the following reasons: Peas are self-pollinating. ADVERTISEMENTS: Mendel chose garden pea (Pisum sativum) as plant material for his experiments, since it had following advantages: 1. Practice. Useful features of peas include their rapid life cycle and the production of lots and lots of seeds. They served as a control for the main garden experiment in case of possible disturbance by insects. Among the many species on which Mendel worked, he selected pea because the plants and seeds have a wide array of distinct features that occur in two easily identifiable forms (e.g. Pea plants make a convenient system for studies of inheritance, and they are still studied by some geneticists today. What did Mendel call the two kinds of traits exhibited by the pea plants (one coming from the father, one from the mother)? Among those that visit the pea plant, the beetle species Bruchus pisi could be dangerous for the experiment if it appears in large numbers. As a result, the newly grown plant remains pure. Other, Biology. Peas are annual plants. 0. These were the traits that Mendel was interested in studying. This study showed that one in four pea plants had purebred recessive alleles, two out of four were hybrid and one out of four were purebred dominant. This is one of the main reasons for choosing the Pea plant. This indicates how strong in your memory this concept is. Contributions of Mendel in the Field of Genetics, Define and Describe on Dominant Characteristics, Road infrastructure and driver behavior can create complex road networks, Scientists develop Single Photons from a Silicon Chip for quantum light particles, Physicists use antiferromagnetic rust for Faster and Efficient Information Transfer, Crab armies can be a key issue in coral wall preservation, Beaches cannot be extinct if sea levels continue to rise. And lots and lots of pea plants. (iv) Since pea-plant is self-pollinated, the mixing of any other characters is not easily possible. Pea plants had the following characteristics: Useful features of peas include their rapid life cycle and the production of lots and lots of seeds. 6th - 8th grade. (vi) Comparative hereditary characteristics is present, thus variation can occur. (iii)They are easily self- and cross-pollinated and produces many offspring in one cross. (ii) As the life time of each pea plant is short, the result of hybridization can be achieved within a very short tame; (iii) The flowers of pea plants are bisexual. During the mid-nineteenth century, Johann Gregor Mendel experimented with pea plants to develop a theory of inheritance. self-pollination and self-fertilization is possible.

The hybrids of the pea plants produced by cross-pollination are perfectly fertile. 2. They exhibit only a single trait. Subsequently, in 1851 he decided to study botany, physics, chemistry and history at the University of Vienna. MEMORY METER. The pea plant has seven traits that are visible and easy to study. Answer: They reproduce sexually. These traits were petal color, seed shape, flower position, stem shape, pod color, pod shape and stem length. Preview this quiz on Quizizz. 2 years ago.
