Which of the following statement is incorrect?
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 ______
Give the pair of contrasting traits of the following characters in the pea plant and mention which is dominant and recessive
- yellow seed
- round seed
