Answer

yyRr Explanation 1. Identify Parental Genotypes The parental genotypes are YyRr and yyrr. 2. Determine Possible Gametes YyRr can produce gametes: Yr, yR, YR, yr. yyrr can only produce yr. 3. Identify Recombinant Offspring Recombinant offspring have new combinations of alleles not found in the parents. Cross the gametes: - Yr \times yr = Yyrr - yR \times yr = yyRr - YR \times yr = YyRr - yr \times yr = yyrr 4. Select Recombinant Types Recombinant types differ from both parents' combinations (YyRr and yyrr): - yyRr is recombinant. - Yyrr is recombinant.

Explanation

1. Identify Parental Genotypes<br /> The parental genotypes are $YyRr$ and $yyrr$.<br /><br />2. Determine Possible Gametes<br /> $YyRr$ can produce gametes: $Yr$, $yR$, $YR$, $yr$. <br /> $yyrr$ can only produce $yr$.<br /><br />3. Identify Recombinant Offspring<br /> Recombinant offspring have new combinations of alleles not found in the parents. Cross the gametes:<br />- $Yr \times yr = Yyrr$<br />- $yR \times yr = yyRr$<br />- $YR \times yr = YyRr$<br />- $yr \times yr = yyrr$<br /><br />4. Select Recombinant Types<br /> Recombinant types differ from both parents' combinations ($YyRr$ and $yyrr$):<br />- $yyRr$ is recombinant.<br />- $Yyrr$ is recombinant.
