The genotypes of the two parents are as follows:
- The yellow flowered hybrid entire plant is heterozygous for flower color, having one yellow allele (Y) and one red allele (R), and is homozygous for leaf margin pattern, having two copies of the dominant entire allele (E).
- The orange flowered lobed plant is homozygous for flower color, having two copies of the recessive orange allele (O), and is heterozygous for leaf margin pattern, having one copy of the dominant entire allele (E) and one copy of the recessive lobe allele (L).
When these two parents are crossed, the possible genotypes and phenotypes of the offspring can be determined using Punnett square analysis.
- Genotypes of the offspring:
- 25% will be YOEE (yellow flowers, entire leaf margin)
- 25% will be YOLE (yellow flowers, lobe leaf margin)
- 25% will be ROEE (red flowers, entire leaf margin)
- 25% will be ROLE (red flowers, lobe leaf margin)
- Phenotypes of the offspring:
- 50% will have yellow flowers
- 50% will have red flowers
- 75% will have entire leaf margin
- 25% will have lobe leaf margin
These ratios are based on the inheritance patterns of the flower color and leaf margin genes, as described in the question.
