Directions: In the following questions, a statement of assertion (A) ...
Assertion: A geneticist crossed a pea plant having violet flowers with a pea plant having white flowers, and he got all violet flowers in the first generation.
Reason: White color gene is not passed on to the next generation.
The correct answer is option 'C' - Assertion (A) is true but reason (R) is false.
Explanation:
Mendel's Law of Dominance states that when two pure breeding individuals with contrasting traits are crossbred, the offspring in the first generation (F1 generation) will exhibit the dominant trait.
In this case, the geneticist crossed a pea plant with violet flowers (VV) with a pea plant with white flowers (vv). According to Mendel's Law of Dominance, the violet flower trait is dominant over the white flower trait.
Therefore, in the F1 generation, all the offspring will have violet flowers. This is because each offspring inherits one allele from each parent, and since the violet flower allele (V) is dominant, it will mask the presence of the white flower allele (v). Hence, all the offspring will have the genotype Vv, resulting in violet flowers.
However, the reason given in the statement is incorrect. The white color gene is indeed passed on to the next generation, but it is masked by the presence of the dominant violet color gene. In the F1 generation, the white color gene (v) is present in the genotype of the offspring (Vv), but it is not expressed phenotypically because the dominant violet color gene (V) is expressed instead.
In subsequent generations, if the F1 generation plants are self-pollinated or cross-pollinated, the white color gene can reappear in the offspring if both parents carry the recessive white color allele. This is because in the F2 generation, there is a possibility of the violet color allele and the white color allele segregating and recombining in different combinations, resulting in some offspring having white flowers.
Therefore, the assertion is true because all the offspring in the F1 generation will have violet flowers, but the reason is false because the white color gene is passed on to the next generation, although it may not be expressed phenotypically in the presence of the dominant violet color gene.
Reason: White color gene is not passed on to the next generation.
The correct answer is option 'C' - Assertion (A) is true but reason (R) is false.
