Phenotype
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?
Genes which code for a pair of contrasting traits are known as ______.
If a round, green seeded pea plant (RRyy) is crossed with a wrinkled, yellow seeded pea plant (rrYY), the seeds produced in the F1 generation 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 ______
What is the scientific name of the pea plant that Mendel used for his experiments?
