Question

1. identify the genotype for each numbered item. 2. rryy 3. ry 4. identify the phenotype for item 4. smooth yellow wrinkled yellow smooth green wrinkled green

Explanation:

Step1: Understand genetic symbols

In genetics, R is often for smooth (dominant) and r for wrinkled (recessive), Y for yellow (dominant) and y for green (recessive).

Step2: Analyze genotype 1 (RRYy)

RR gives smooth phenotype (since R is dominant for shape) and Yy gives yellow phenotype (since Y is dominant for color). So phenotype is smooth yellow.

Step3: Analyze genotype 2 (Rryy)

Rr gives smooth phenotype and yy gives green phenotype. So phenotype is smooth green.

Step4: Analyze genotype 3 (RrYy)

Rr gives smooth phenotype and Yy gives yellow phenotype. So phenotype is smooth yellow.

Step5: Analyze genotype 4 (rrYy)

rr gives wrinkled phenotype and Yy gives yellow phenotype. So phenotype is wrinkled yellow.

Answer:

1. smooth yellow
2. smooth green
3. smooth yellow
4. wrinkled yellow
