Answer :
To determine the expected genotypic ratio of the offspring when crossing a red flower (RR) with a white flower (WW), we can follow these steps:
1. Determine the Genotypes of the Parent Flowers:
- Red flower has the genotype RR.
- White flower has the genotype WW.
2. Perform the Cross:
- Since the alleles exhibit incomplete dominance, we cross the RR (red) with WW (white).
3. Predict the Offspring's Genotypes:
- Each offspring receives one allele from each parent. Therefore, all offspring will receive one R allele from the red parent and one W allele from the white parent.
- As a result, all offspring will have the RW genotype.
4. Determine the Genotypic Ratio:
- Since all offspring are RW, the genotypic ratio is 0 RR: 4 RW: 0 WW.
By following these steps, we can see that the expected genotypic ratio is option A: 0 RR: 4 RW: 0 WW.
