The gene for flower color in snapdragons displays incomplete dominance. Snapdragons homozygous for the allele for red flower color have the genotype F^RF^R and have red flowers. Snapdragons homozygous for the allele for white flower color have the genotype F^WF^W and have white flowers. Heterozygous snapdragons with the genotype F^RF^W have pink flowers. A snapdragon that has red flowers is crossed with a different snapdragon that has pink flowers. What percentage of the offspring is expected to have red, white, and pink flowers? red flowers: % white flowers: % pink flowers: %

If the allele 'R' for red flowers is incompletely dominant over the allele 'r' for white flowers, then the heterozygous genotype of 'Rr' will result in pink flowers (rather than red). Write the genotypes of the parents for the following crosses, given the phenotype. Then complete the Punnett square, calculate the resulting genotypic and phenotypic ratios, and answer the associated question for each cross. 8. red parent ________ x pink parent ________ genotypic ratio: phenotypic ratio: What is the probability that this cross will produce a pink flower? 9. pink parent ________ x white parent ________ genotypic ratio: phenotypic ratio: What is the probability that this cross will produce a pink flower? 10. pink parent ________ x pink parent ________ genotypic ratio: phenotypic ratio: What is the probability that this cross will produce a pink flower?
