Question

spooner is homozygous dominant for his yellow color (yy). wendy has the recessive trait, blue color (yy). spooner wendy phenotype probability (%) yellow color: blue color:

Explanation:

Step1: Count total offspring

From the Punnett square, there are 4 offspring (Yy, Yy, Yy, Yy).

Step2: Determine yellow phenotype

All 4 offspring have genotype Yy. Since Y is dominant, all show yellow phenotype. So yellow count = 4.

Step3: Calculate yellow percentage

Yellow percentage = $\frac{4}{4} \times 100\% = 100\%$.

Step4: Determine blue phenotype

No offspring has genotype yy (blue), so blue count = 0.

Step5: Calculate blue percentage

Blue percentage = $\frac{0}{4} \times 100\% = 0\%$.

Answer:

Yellow color: 100%
Blue color: 0%
