Explanation:

Step1: Determine the alleles for eyes

The allele from the parent with \(GY\), \(Gy\), \(GY\), \(Gy\) is \(Gy\) (since the row is \(gy\) and the column is \(Gy\) for the shaded box). The \(G\) is for gold eyes (dominant) and \(g\) is for silver eyes. Since \(G\) is present, the eye - color is gold.

Step2: Determine the alleles for feathers

The allele combination for feathers: from the row \(gy\) (so \(y\)) and column \(Gy\) (so \(y\)). The \(Y\) is for yellow feathers (dominant) and \(y\) is for brown feathers. Since we have \(yy\), the feather - color is brown.

Answer:

Gold eyes and brown feathers
