But when you cross a "Texas Beauty" yellow with the yellow variety "Jealousy," you get a 9:7 ratio of red to yellow flowers! What can you conclude from these results? The red allele is dominant to the yellow allele. There is a mutation in the gene for yellow pigment in the "Jealousy" variety. C. There are epistatic interactions between at least two genes for rose pigment. D. There is no recessive allele for the red pigment
