The Lubber grasshopper is a very large grasshopper, and is black in color with stripes. The color of the stripes exhibit incomplete dominance. Red stripes or yellow stripes may be expressed; however, when alleles are mixed, orange stripes are expressed. What will be the genotypic and phenotypic ratios be for the offspring of two parents that both have orange stripes. Genotype:
Phenotype:

Explanation:

Let R be the allele for red stripes.

Let r be the allele for yellow stripes.

Parental phenotypes:

Orange stripes * Orange stripes

Parental genotypes:

Rr * Rr

Gametes:

(R)(r) * (R)(r)

Using a Punnett's Square, we get

F1 generation genotypes:

RR : Rr : rr = 1 : 2 : 1

F1 generation phenotypes:

Red : Orange : Yellow = 1 : 2 : 1.

true is the final answer!

the correct answer should be false
