Answer :
Let's solve this step-by-step to determine which cross between parent plants represents the given scenario, where one parent is heterozygous with yellow-colored pods, and the other is homozygous with green-colored pods.
### Step 1: Identify Genotypes of the Parent Plants
1. Heterozygous with Yellow-colored Pods (Parent 1):
- Heterozygous means having two different alleles for a particular gene.
- If the allele for yellow pods is represented by 'Y' (dominant) and the allele for green pods is represented by 'y' (recessive), then the genotype for this parent is `Yy`.
2. Homozygous with Green-colored Pods (Parent 2):
- Homozygous means having two identical alleles for a particular gene.
- Because green pods are recessive, the genotype must be `yy`.
### Step 2: Represent the Cross between the Parent Plants
Parent 1 (heterozygous, yellow-colored pods): `Yy`
Parent 2 (homozygous, green-colored pods): `yy`
The cross can be written as:
[tex]\[ Y y \times y y \][/tex]
### Step 3: Determine the Possible Offspring Genotypes
When we perform the cross, each parent will contribute one allele to their offspring. Here are the possible combinations:
- Parent 1 (`Yy`) can contribute either `Y` or `y`.
- Parent 2 (`yy`) can contribute only `y`.
So, the possible offspring genotypes are:
- `Y` from Parent 1 and `y` from Parent 2: `Yy` (Yellow pods)
- `y` from Parent 1 and `y` from Parent 2: `yy` (Green pods)
Hence, the possible genotypes of the offspring will be:
[tex]\[ \text{Yy, Yy, yy, yy} \][/tex]
### Conclusion
The cross between parent plants, where one plant is heterozygous with yellow-colored pods and the other is homozygous with green-colored pods, is represented by:
[tex]\[ Y y \times y y \][/tex]
So the correct representation among the given options is:
[tex]\[ Y y \times y y \][/tex]
