Explanation:

Step1: Analyze top - left box

The top - left box is formed by the combination of the allele from the top row (\(y\)) and the allele from the left - hand column (\(Y\)). When combining alleles in a Punnett square, we simply put the two alleles together. So, the genotype for the top - left box is \(Yy\).

Step2: Analyze top - right box

The top - right box is formed by the combination of the allele from the top row (\(y\)) and the allele from the left - hand column (\(Y\)). Combining these two alleles gives us the genotype \(Yy\).

Step3: Analyze bottom - left box

The bottom - left box is formed by the combination of the allele from the top row (\(y\)) and the allele from the left - hand column (\(Y\)). Combining these alleles, we get the genotype \(Yy\). Wait, no, wait. Wait, the left - hand column for the bottom row is \(Y\) and the top row allele for the bottom - left box is \(y\)? Wait, no, let's re - examine. The top row has two \(y\)s (columns 1 and 2), and the left - hand column has two \(Y\)s (rows 1 and 2). So for the first row (row 1, with allele \(Y\)) and column 1 (allele \(y\)): genotype \(Yy\). Row 1, column 2 (allele \(y\)): genotype \(Yy\). Row 2 (allele \(Y\)), column 1 (allele \(y\)): genotype \(Yy\). Row 2, column 2 (allele \(y\)): genotype \(Yy\)? Wait, no, maybe I made a mistake. Wait, the parent genotypes: if the top row (female or male) has genotype \(yy\) (since both alleles are \(y\)) and the left - hand column (male or female) has genotype \(YY\) (since both alleles are \(Y\)). Then, when we do the Punnett square, each offspring will have one \(Y\) from the \(YY\) parent and one \(y\) from the \(yy\) parent. So all four boxes should have genotype \(Yy\).

So let's correct the step - by - step:

Step1: Top - left box (row 1, column 1)

Row allele: \(Y\), column allele: \(y\). Genotype: \(Y + y=Yy\).

Step2: Top - right box (row 1, column 2)

Row allele: \(Y\), column allele: \(y\). Genotype: \(Y + y = Yy\).

Step3: Bottom - left box (row 2, column 1)

Row allele: \(Y\), column allele: \(y\). Genotype: \(Y + y=Yy\).

Step4: Bottom - right box (row 2, column 2)

Row allele: \(Y\), column allele: \(y\). Genotype: \(Y + y = Yy\).

Answer:

All four boxes (top - left, top - right, bottom - left, bottom - right) should have the genotype \(Yy\). So the correct genotypes for each box are:

Top - left: \(Yy\)

Top - right: \(Yy\)

Bottom - left: \(Yy\)

Bottom - right: \(Yy\)
