Question
Why did Mendel select pea plants for his experiment?
Solution 1
Mendel selected pea plants for his experiment because of the following reasons :
- A pea plant has many contrasting characters.
- Self-fertilization takes place in pea plants and so it is possible to get a pure line of traits.
- Flowers are bisexual and hermaphrodite. Therefore, cross-pollination is achieved easily.
Solution 2
- The pea plant is self-pollinating and so it is very easy to raise pure breeding individuals.
- It has a short life span, as it is annual.
- It is easy to cross-pollinate.
- It has deeply defined contrasting characters.
- The flowers are bisexual.

Which of the following are reasons for Mendel’s success?
- Usage of pure lines or pure breeding varieties

- Maintenance of statistical records of experiments
- Knowledge of linkage and incomplete dominance
Two pea plants one with round green seeds (RRyy) and another with wrinkled yellow (rrYY) seeds produce F1 progeny that have round, yellow (RrYy) seeds. When F1 plants are selfed, the F2 progeny will have new combination of characters. Choose the new combination from the following:
- Round, yellow
- Round, green
- Wrinkled, yellow
- Wrinkled, green

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?
