Mendel selected pea plants for his experiments due to following reasons: Pea is an annual plant and hence many generations can be studied in a short duration. 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”. Inheritance involves the passing of discrete units of inheritance, or genes, from parents to offspring. He wanted clear cut alternate forms of traits (yellow vs green, round vs wrinkled, etc. (ii) They are self-pollinating, and thus, self and cross pollination can easily be performed. (i)When the F1 generation plants were self - fertilized, he observed that in the plants of second - generation F2 both tall plants and dwarf plants were present. Gartner worked with plants in his experiments, including peas, which may have inspired Mendel to work with the same plant. Question: Why did Mendel use pea plants in his experiments?

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. (ii) It had well defined and contrasting characters. Example: Mendel’s monohybrid between Tall pea plant and dwarf pea plant: In an artificial cross between two pure breeding plants (stock or parent), one tall plant and the other dwarf plant were cross pollinated. (a) Mendel selected garden pea plant for his experiments because of the following characteristics: (i) The flowers of this plant are bisexual. As a result, they can either self-pollinate themselves or cross-pollinate with another plant. Self-pollination happens before the flowers open, so progeny are produced from a single plant. Pure breeds were important in his experiment so he could record accurate results. In 1843 he entered the convent of Brünn and three years later was ordained as a priest.

Gregor Mendel chose pea plants because they produce many offspring, reproduce quickly, and can self-fertilize. In Mendel's first set of experiments, he experimented with just … 5. The law of segregation states that the two alleles of a single trait will separate randomly, meaning that there is a 50% either allele will end up in either gamete. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Mendel’s seminal work was accomplished using the garden pea, Pisum sativum, to study inheritance. But Mendel really had no way of knowing that at the time. Mendel cross-bred tall and dwarf pea plants, green and yellow peas , purple and white flowers, wrinkled and smooth peas, and a … Through the selective cross-breeding of common pea plants (Pisum sativum) over many generations, Mendel discovered that certain traits show up in offspring without any blending of parent characteristics. Seed traits. Mendel studied inheritance in peas (Pisum sativum). Module 5 DQ 2 The power of inheritance of traits. The seeds obtained from cross pollination are cultivated to developed plants which represented the first filial generation (F1).
