Who among the following is called father of genetics?
______ pairs of contrasting characters in pea plants were studied by Mendel in his experiments.
To study the natural phenomenon of inheritance, Mendel selected pea plants. Which of the following properties were suitable for their studies?
(i) Plants would easily self-pollinate or cross-pollinate in nature.
(ii) Plants were easily grown in garden soil with a considerably shorter generation time.
(iii) Pea plants do not require true-breeding for hybridization experiments.
(iv) Many parts of the plant such as pod, seed, flower, cotyledons showed distinct phenotypes.
Read the following and answer from given below:
Prashant wanted to find the genotype of a pea plant bearing purple coloured flowers in his kitchen garden. For this, he crossed purple-flowered plants with white-flowered plants. As a result, all plants which were produced had purple flowers only. Upon selfing these plants, 75 purple flower plants and 25 white flowers plants were produced. Now, he can determine the genotype of a purple-flowered plant by crossing it with a white-flowered plant.
In white-flowered plants, the allele is expressed in ______
How many pairs of contrasting characters in pea bad were chosen by Mendel?
If a cross between two individuals produces offspring with 50% dominant character (A) and 50% recessive character (a) then the Genotypes of parents are:
Assertion: Height in pea plants is controlled by the efficiency of enzymes and is thus genetically controlled.
Reason: Cellular DNA is the information source for making proteins in the cell.
