AIPMT 2015: How many pairs of contrasting characters in pea plants were studied by Mendel in his experiments? (viii) Contrasting characteristics, such as tall-short, etc occurs a pea plant. Self-fertilization takes place in pea plants and so it is possible to get a pure line of traits. A relatively unknown teacher and monk, Gregor Mendel, published a study of pea plants in 1866. 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.

Thus, while green seedpods are dominant and yellow seedpods are recessive, the recessive lineage does not disappear completely. Mendel used a number of contrasting characters for garden pea. There are seven inherited characters having two variants (alleles) as, dominant (expressive) and recessive (hidden) allele. How many pairs of contrasting characters in pea plants were studied by Mendel in his experiments? In fact, a light frost in the spring may even be beneficial. Why did Mendel select pea plant for his experiments? (iv) In later experiments, Mendel also crossed pea plants with two contrasting characters known as dihybrid cross. Seedpods on pea plants are either yellow or green. Mendel discovered that no yellow seedpods were present in the offspring of crossbred green pod and yellow pod plants. Mendel focused on the different traits, or characters, that he noticed pea plants exhibiting in a binary manner. Mendel noted seven pairs of such contrasting characters in garden pea plant. 2. a. 4. Yellow seedpods are genetically recessive. Cool-Season The pea plant may adapt to a variety of growing conditions, but it prefers cool, damp weather, with temperatures ranging from 60 to 75 degrees F.

Ch Mendel was successful in formulating the laws of inheritance where as his predecessors where not because . Through breeding of multiple generations of pea plants, Mendel discovered that purple flowers are dominant and white flowers are recessive. Green seedpods are genetically dominant. 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). 2. True-breeding pea plants showing contrasting character for flower position were cross-bred. After they have planted and grown five plants, Mendel asks students how many distinguishing traits they see in the plants. (ix) The life span of a pea plant is short, thus many generations can be obtained in a single growing season. "Asking About Life;" Allan J.
