Which one from those given below is the period for Mendel's hybridization experiments?
In the human blood grouping, the four basic blood types are type A, type B, type AB, and type O. They are ______
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 ______

Give reasons for the appearance of new combinations of characters in the F2 progeny.
Mendel blended his knowledge of science and mathematics to keep count of the individuals exhibiting a particular trait in each generation. He observed a number of contrasting visible characters controlled in pea plants in a field. He conducted many experiments to arrive at the laws of inheritance.
- What do the F1 progeny of tall plants with round seeds and short plants with wrinkled seeds look like?
- Name the recessive traits in the above case.
- Mention the type of the new combinations of plants obtained in F2 progeny along with their ratio, if F1 progeny was allowed to self-pollinate.
OR
If 1600 plants were obtained in F2 progeny, write the number of plants having traits:
- Tall with round seeds.
- Short with wrinkled seeds.
Write the conclusion of the above experiment.
In parents, mendelian factors occur in pairs, but they segregate during ______.
