Question

a certain species of grasshopper can have red stripes, yellow stripes, or red and yellow stripes. an rr grasshopper has red stripes, a yy grasshopper has yellow stripes, and an ry grasshopper has red and yellow stripes. a grasshopper with red stripes mates with a grasshopper with red and yellow stripes. what ratio would be expected in the phenotypes of their offspring? 2 with red stripes: 2 with red and yellow stripes all with yellow and red stripes 2 with red stripes: 2 with yellow stripes all with red stripes

Explanation:

Step1: Determine the genotypes of the parents

The grasshopper with red stripes has genotype \(RR\). The grasshopper with red and yellow stripes has genotype \(RY\).

Step2: Set up the Punnett square

The possible gametes for \(RR\) are \(R\) and \(R\). The possible gametes for \(RY\) are \(R\) and \(Y\).

	\(R\)	\(Y\)
\(R\)	\(RR\)	\(RY\)

Step3: Analyze the genotypes and phenotypes of the offspring

The genotypes of the offspring are \(RR\) and \(RY\). The phenotype of \(RR\) is red stripes and the phenotype of \(RY\) is red and yellow stripes. There are 2 \(RR\) (red - striped) and 2 \(RY\) (red - and - yellow - striped) in the Punnett square.

Answer:

2 with red stripes: 2 with red and yellow stripes
