B.Neuronsincorrect answer (Public domain; LadyofHats via Wikimedia.org) Controlling Pollination . Mendel focused on the different traits, or characters, that he noticed pea plants exhibiting in a binary manner. After they have planted and grown five plants, Mendel asks students how many distinguishing traits they see in the plants. Each of these characters such as height, seed shape, seed colour, etc., had two sharply defined and contrasting traits (e.g., tallness and dwarfness, round seed and wrinkled seed, yellow seed and green seed). Mendel’s hybridization experiments demonstrate the difference between phenotype and genotype. characteristics included plant height, seed texture, seed color, flower color, pea-pod size, pea-pod color, and flower position. AIPMT 2015: How many pairs of contrasting characters in pea plants were studied by Mendel in his experiments? Therefore, cross pollination is achieved easily.

Mendel used a number of contrasting characters for garden pea. 1 answer. Self-fertilization takes place in pea plants and so it is possible to get a pure line of traits. For the characteristic of flower color, for example, the two contrasting traits were white versus violet. To fully examine each characteristic, Mendel generated large numbers of F 1 and F 2 plants and reported results from thousands of F 2 plants. Terminal pods are located at the ends of the stems. As per Mendel's findings, smooth peas are dominant texturally, and wrinkled pods are recessive. Mendel discovered that no yellow seedpods were present in the offspring of crossbred green pod and yellow pod plants.

The seeds produced by this cross were grown to develop into plants of Fillial 1 progeny or F 1 -generation (F 1 -plants). A flower has two possible positions on a pea plant, terminal and axial. 3. It is easy to cross-pollinate. A relatively unknown teacher and monk, Gregor Mendel, published a study of pea plants in 1866. Thus, a purple flower in the axial position is a doubly dominant trait in pea plants, and a white flower in the terminal position is a doubly recessive trait.

Through breeding of multiple generations of pea plants, Mendel discovered that purple flowers are dominant and white flowers are recessive. 3.Flowers are bisexual and hermaphrodite. C The Characteristics of the pea plant studied by Mendel are also called as traits. Gregor Johann Mendel, known as the Father of Genetics. - Sarthaks eConnect | Largest Online Education Community True-breeding pea plants showing contrasting character for flower position were cross-bred. A yellow seed albumen is dominant, and a green seed albumen is recessive. The observable traits expressed by an organism are referred to as its phenotype. Pea plant flowers are either white or purple. The hybrids of the pea plants produced by cross-pollination are perfectly fertile. Seed colour. His work can be found on various websites. It has deeply defined contrasting characters. An organism’s underlying genetic makeup, consisting of both physically visible and non-expressed alleles, is called its genotype. Yellow seedpods are genetically recessive. As per Mendel's findings, axially positioned flowers are dominant in pea plants, and terminally positioned flowers are recessive. Mendel selected seven varieties of garden pea plants differing in seven pairs of contrasting characters. a.

C.White blood cells answe Thus, if two pea plants are bred, white flowers will be present in offspring only if both parents pass on a white flower allele. All three varieties share several common characteristics. Mendel studied a total of seven traits in pea plants. In addition to seedpod color, flower color and flower position, the geneticist looked at the texture of seeds, seed albumen, the length of the plant stem and the form of ripe pea pods. Axial flowers grow near the middle of the plant. 2. (ix) The life span of a pea plant is short, thus many generations can be obtained in a single growing season. 4.
