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.
Which of the following cannot be derived from the crosses done by Prashant?
Why did Mendel choose pea plant for his experiments?
In his cleric experiments on pea plants, Mendel did not use:
An organism with two identical alleles is
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.
