Answer (1) 7 pairs of contrasting characters in pea plant were studied by Mendel in his experiment. Mendel conduct experiments on how many pea plants ? (d) He selfed the (hybrid) plants of F 1 progeny. Monohybrid Cross: When only one pair of contrasting traits is studied in the cross, it is called monohybrid cross. Law of segregation; Law of dominance; Law of independent assortment; Law of unit characters; Answer:3. Be the first to write the explanation for this question by commenting below. 9. 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. It is the site of production of proteins.

These characters can be easily distinguished from each other such as plant height (tall and dwarf), shape of seed (round and wrinkled) colour of seeds (green and yellow) etc. Mendel formulated the laws of heredity considering 7 pairs of contrasting characters in the pea plant, if he had studied an eighth pair, the law which would have been altered is. So the tall ones can grow up to five to six feet tall. Identify the wrong statement with reference to the gene T that controls ABO blood groups. Mendel selected 14 true-breeding pea plant varieties, as pairs which were similar except for one character with contrasting traits. In this way Mendel selected 7 pairs of contrasting traits in pea plant and studied the inheritance of these contrasting traits in various generations of pea plant. Color of seed coat. 1. © Which of the following endoparasites of humans does show viviparity?

Answer: Explaination: Colour of the pod, shape of the pod, colour of the flower, position of the flower, shape of the seed. Which of the following characteristics is mainly responsible for diversification of insects on land? 7 Characters Mendel studied in sweet pea are . (5) Each pea plant produced many seeds in one generation. In monohybrid cross for character height; Mendel crossed a homozygous tall pea plant (TT) … All the hybrid plants were tall. 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. Options (a) 1 (b) 2 (c) 3 (d) 4. Mammals are broadly classified into two broad categories:(i) Protheria are egg laying mammals(ii) Theria are placental mammals, which can be further divided into Metatheria and Eutheria. pls mark as brainliest ️ ️ . 34 types of 10,000 pea plants. 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.
