Questions: A parent with a genotype of RrYy can produce which of the following gametes? Rr Yy IY ry ryy RY Ry

The question asks which gametes can be produced by a parent with the genotype $Rr Yy$. To determine this, we need to consider the possible combinations of alleles that can be passed on from each gene.

1. The parent has two genes: one with alleles R and r, and another with alleles Y and y.
2. Each gamete will receive one allele from each gene.

Let's list the possible combinations:

• From the R/r gene, the gamete can receive either R or r.
• From the Y/y gene, the gamete can receive either Y or y.

By combining these possibilities, the potential gametes are:

1. RY
2. Ry
3. rY
4. ry

Now, let's evaluate each option:

• Rr Yy: This is not a gamete; it represents a genotype with two alleles from each gene, which is not possible in a single gamete. Therefore, this is incorrect.
• IY: This is not a valid gamete because "I" is not an allele present in the parent's genotype. Therefore, this is incorrect.
• ry: This is a valid gamete, as it contains one allele from each gene (r from R/r and y from Y/y). Therefore, this is correct.
• ryy: This is not a valid gamete because it contains two alleles from the Y/y gene, which is not possible in a single gamete. Therefore, this is incorrect.
• RY: This is a valid gamete, as it contains one allele from each gene (R from R/r and Y from Y/y). Therefore, this is correct.
• Ry: This is a valid gamete, as it contains one allele from each gene (R from R/r and y from Y/y). Therefore, this is correct.

In summary, the correct gametes that can be produced by a parent with the genotype $Rr Yy$ are:

• ry
• RY
• Ry
