The lubber grasshopper is a very large grasshopper, and is black with red and yellow stripes. Assume that red stripes are expressed from the homozygous RR genotype, yellow stripes from the homozygous rr genotype and both from the heterozygous Rr genotype. What will be the phenotypic ration of the F1 generation resulting from a cross of two grasshoppers, both with red and yellow stripes (Rr x Rr)? What would be the genotypic ration of the F1 generation? What phenotypes would be produced by crossing a grasshopper with both color stripes and one with only yellow stripes?
