Example: Tall/Short Plants for Stem height. Bouché used 4 of Mendel’s 7 traits to classify all the varieties (seed shape, plant length (=height), pod type and flower colour), and in addition he described the colour of the seeds, pod colour (green vs yellow) and flower position (terminal vs axial) for a few of the varieties, completing the set of seven character states that Mendel used. Mendel conducted breeding experiments with garden peas: (a) He studied plants (pure) of a tall/short varieties. Contact us on below numbers. Then Mendel performed hundreds of crosses. Seed Color 4. Flower location. Pod shape. Pod Shape 6. First-generation (F1) progeny only showed the dominant traits, but recessive traits reappeared in the self-pollinated second-generation (F2) plants in a 3:1 ratio of dominant to recessive traits.

Seven pairs of contrasting characters were chosen for his study. 5. Position of flower. 7. Time it out for real assessment and get your results instantly. Rediscovery of Mendelism; Genetic Terminology; Monohybrid Cross; Dihybrid Cross; Mendel’s Law of Inheritance; Back Cross Out Cross; Test Cross; Importance of mendel’s law of inheritance. Characters. The short ones will be one and a half to two feet tall. yellow – dominant green – recessive (ii) round – dominant wrinkled – recessive. Color of pod. Chetan & Nikunj 7,604 views.

Why did Mendel choose pea plant for his experiments. (6) The garden pea plants … It also help in production of pure line or homozygous plant. Appearance of tall character in both the F, and F, shows that it is a dominant character. Flower Color 6. The pea flower has anthers and a stamen which are very close together. For monohybrid cross, let us take example of monohybrid cross for stem height, i.e. 2.
