Predict the genotype and phenotype of the following cross in pea.
tt x TT
(Capital letters show dominance)
Flowers of the garden pea are bisexual and self-pollinated. Therefore, it is difficult to perform a hybridization experiment by crossing a particular pistil with the specific pollen grains. How Mendel made it possible in his monohybrid and dihybrid crosses?
______ pairs of contrasting characters in pea plants were studied by Mendel in his experiments.
Mendel studied interitance of seven pairs of traits in pea which can have 21 possible combinations. If you are told that in one of these combinations, independent assortment is not observed in later studies, your reaction will be.
Pure-bred pea plant A is crossed with pure-bred pea plant B. It is found that the plants which look like A do not appear in the F1 generation but re-emerge in the F2 generation. Which of the plant's A and B are tall and dwarf?
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.
To determine the genotype of a purple-flowered plant, Prashant crossed this plant with a white-flowered plant. This cross represents a ______

In white-flowered plants, the allele is expressed in ______
If two pea plants having red (dominant) coloured flowers with unknown genotypes are crossed, 75% of the flowers are red and 25% are white. The genotypic constitution of the parents having red coloured blowers will be:
In order to obtain the F1 generation Mendel pollinated a pure-breeding tall plant with a pure breeding dwarf plant. But for getting the F2 generation, he simply self-pollinated the tall F1 plants. Why?
Which one of the following cannot be explained on the basis of Mendel’s Law of Dominance?
