Answer:
Genotype: 100% or 4/4 of the progeny will be heterozygous for the trait, Yy. 
Explanation:
<u>Available data:</u>
- Two plants differ in the seed color they produce. 
- One plant produces green seeds, the other produces yellow seeds. 
- Yellow is the dominant phenotype, over green which is the recessive phenotype
- The parental plants are true-breeding
Let us say that the allele Y expresses yellow color and is dominant over the allele y which expresses the green color and in the recessive one.
