The given question is related to Mendelian genetics, which deals with the inheritance of traits from parents to offspring. In this question, we are given a homozygous red-flowered pea plant (RR) and a homozygous white-flowered pea plant (rr), and we need to determine the possible offspring.
Explanation:
- Homozygous refers to having two identical alleles for a particular gene (in this case, flower color).
- The allele for red flower color is dominant (R), and the allele for white flower color is recessive (r).
- Therefore, the homozygous red-flowered plant has two dominant alleles (RR), and the homozygous white-flowered plant has two recessive alleles (rr).
- When these two plants are crossed, the offspring will inherit one allele from each parent, resulting in the following possible genotypes: RR, Rr, and rr.
- However, since the dominant allele (R) masks the recessive allele (r) in the heterozygous state (Rr), the only possible phenotype (observable trait) is red flower color.
- Therefore, all the offspring (100%) will have red flowers.
Conclusion:
- The correct answer is option C, all red-flowered.
- This is because the dominant allele (R) for red flower color masks the recessive allele (r) for white flower color in the heterozygous state (Rr).
- Therefore, even though some of the offspring may have the genotype Rr, they will still exhibit the dominant phenotype (red flowers).

YES ALL RED will be in f1
TT CROSS tt will give all tall Tt
THE GIVEN FLOWER IS PEA SO PINK (INCOMPLETE DOMINANCE ex Snapdragon )NOT POSSIBLE .
@ law of dominance as proposed by Mendel.
