Easy to Cultivate – It grew well in his garden. Pea Plants. ADVERTISEMENTS: The self fertilization through many generations helps in easily obtaining the pure line with constant trait in pea plants. The pea flower is … 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. The modern understanding of genetics was pioneered by Gregor Mendel, who studied inheritance in many generations and test crosses of pea plants. As the time gap between generations was short, Mendel could raise many generations of a pea within a short time. Pea plants had the following characteristics: Useful features of peas include their rapid life cycle and the production of lots and lots of seeds. Mendel carried out his key experiments using the garden pea, Pisum sativum, as a model system. With his careful experiments, Mendel uncovered the secrets of heredity, or how parents pass characteristics to their offspring. After studying, Mendel returned to the monastery and it was ther… This is done by transferring pollen from the anthers of a pea plant of one variety to the carpel of a mature pea plant of a different variety. the life cycle was completed in one season. ADVERTISEMENTS: Mendel chose garden pea (Pisum sativum) as plant material for his experiments, since it had following advantages: 1. That a trait may not show up in an individual but can still be passed on to the next generation. He noted that each trait had two visible forms that could be easily recognized. (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. 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. Between 1856 and 1863 Mendel cultivated and tested some 29,000 pea plants (i.e., Pisum sativum). They served as a control for the main garden experiment in case of possible disturbance by insects. 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. [Answer] Why did Gregor Mendel study pea plants?They exhibit only a single trait.They produce flowers.They are easy to grow.They reproduce sexually.

Gregor Mendel is considered the father of genetics, due to the contributions he left through his three laws. Gregor Mendel | Biography, Experiments, & Facts | Britannica 16162. MEMORY METER. 2 years ago. These were the traits that Mendel was interested in studying. Mendel can choose some other plant for experiments but he selected pea plant due to some reasons. 5.4). Gregor Mendel DRAFT. (ix) The life span of a pea plant is short, thus many generations can be obtained in a single growing season. Gallery 2: Album Bernay (1876-93) Illustration of Pea Plants. Normally pea plant was self-fertilizing, because petals enclose the reproductive organs till fertilization (Fig. 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. The pea plant has seven traits that are visible and easy to study. This is one of the main reasons for choosing the Pea plant. You may not care much about heredity in pea plants, but you probably care about your own heredity. Pea plants make a convenient system for studies of inheritance, and they are still studied by some geneticists today. In 1843 he entered the convent of Brünn and three years later was ordained as a priest. Mendel worked as a gardener so was used to the varieties of pea in common cultivation. 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. 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. (iv) Since pea-plant is self-pollinated, the mixing of any other characters is not easily possible. (viii) Contrasting characteristics, such as tall-short, etc occurs a pea plant. Among those that visit the pea plant, the beetle species Bruchus pisi could be dangerous for the experiment if it appears in large numbers. His "control" was trying to always match the 3:1 ratio.

(iii)They are easily self- and cross-pollinated and produces many offspring in one cross. Gregor Mendel The Friar Who Grew Peas by Cheryl Bardoe is a must for your living books collection for science! 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. 2. These traits were petal color, seed shape, flower position, stem shape, pod color, pod shape and stem length. They can also be self-pollinated. More importantly for science, however, Mendel cultivated and studied thousands of pea plants in his garden. Peas are annual plants. He picked out the pea plant due to the following reasons: Peas are self-pollinating. (v) Big flower of pea plant makes pollination easier. vii) As the hybrid plants are fully fertile for reproduction, pea plants can reproduce on the tune. […] smooth seed coats) clearly evident in archaeological sites that date back to 6500 BC. The flower is closed typed such that pollination is limited to self. 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. This is one of the main reasons for choosing the Pea … It was not by accident that it became his experimental plant. As the time gap between generations was short, Mendel could raise many generations of a pea within a short time. C. They are easy to grow. Self-pollination occurs easily since the plant is bisexual. You may not care much about heredity in pea plants, but you probably care about your own heredity. Mendel's tasks at his monastery kept him busy. As a result, the newly grown plant remains pure. Color and smoothness of the seeds - grey and round or white and wrinkled, Color of the cotyledons (part of the embryo within the seed) - yellow or green, Position of flowers and pods on the stems.
