Concept

Problem: The lubber grasshopper is a very large grasshopper, and is black with red, orange, or yellow stripes. Assume that red stripes are expressed from the homozygous RR genotype, yellow stripes from the homozygous rr genotype, and orange stripes from the heterozygous Rr genotype. How is stripe color inherited in lubber grasshoppers? You cross two grasshoppers with orange stripes and produce 16 offspring. How many of each phenotype will you have?

FREE Expert Solution

Following Mendelian Genetics, the offspring would always look like one of the two parental varieties. This is due to one allele, having complete dominance over the other. This results in heterozygotes having the same phenotype as the homozygous dominants.
