This is what their offspring looked like: Number of offspring Phenotype 54 Sparkly and magical 49 Not sparkly or magical 15 Sparkly, but not magical 18 Not sparkly, but magical Based on the data above, calculate the ratios of the different genotype combinations of the offspring and determine the genotypes of the parents.
