Question
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 ______
Options
recessive character
dominant character
holandric character
lethal character
Solution
The character i.e., the purple colour of the flowers that appeared in the first filial generation is called the dominant character.
Explanation:
In a first filial generation or heterozygous individuals out of the two factors of alleles representing the alternate traits of a character, one is dominant and expresses itself in the hybrid or F1 generation. The other factor or allele is recessive and does not show its effect in the heterozygous individual.
