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?
One of the reasons why law of segregation of gametes is universally applicable, is ______.
When two genetic loci produce identical phenotypes in cis and trans position, they are considered to be ______.
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.
The character i.e., the purple colour of the flowers that appeared in the first filial generation is called ______
In his cleric experiments on pea plants, Mendel did not use:
