Genotypes: Phenotypes: EE: 0 Red Eyes: 100%. It is not unusual for roses to "change color." A minor change occurs when cooler weather intensifies pink-to-red shades, or age and hot weather fade them. What percentage of the. A heterozygous purple plant is crossed with a homozygous purple plant. the allele P (purple) is dominant. Therefore, every offspring will receive one dominant allele and one recessive allele, or (Pp). Calla liliesparticularly white onessymbolize magnificence, beauty, purity and innocence, and are typically chosen for wedding bouquets. Incomplete dominance is a form of Gene interaction in which both alleles of a gene at a locus are partially expressed, often resulting in an intermediate or different phenotype. . Complete the following crosses and give the genotypic and phenotypic ratios of offspring. 50%. So in this case the red and blue flower petals may combine to form a purple flower. Generation 1 has 200 flowers, generation 2 has 400, generation 3 has 400.
