Question

for white feathers (recessive). according to the punnett square for this cross, what percentage of offspring is predicted to have blue feathers? 25 percent 50 percent 75 percent 100 percent

Explanation:

Step1: Analyze Genotypes (Assumption)

Assume white feathers (\(w\)) are recessive, so white bird is \(ww\). Blue is dominant, so blue bird is \(Ww\) (since if blue were \(WW\), all offspring would be blue, but here we infer a heterozygous cross for 50% chance).

Step2: Create Punnett Square

Cross \(ww\) (white) and \(Ww\) (blue). Gametes: \(ww\) gives \(w, w\); \(Ww\) gives \(W, w\).
Punnett square:

	\(W\)	\(w\)
\(w\)	\(Ww\)	\(ww\)

Step3: Calculate Blue Offspring

\(Ww\) (blue) and \(ww\) (white). \(Ww\) count: 2, total: 4. Percentage: \(\frac{2}{4} \times 100 = 50\%\).

Answer:

50 percent (Option: 50 percent)
