What happened in Mendel's experiments when a pea plant received two different alleles for the same trait?

The pea plant had a phenotype associated with dominant alleles.
Explanation:
The problem tells you that the pea plant is a heterozygote - that is, it has two different alleles of the same gene. The only way that can happen is for one allele to be dominant and the other allele to be recessive.
When a pea plant (or any organism) has at least one dominant allele, it doesn't matter whether the other allele is dominant or recessive. That one single dominant allele is enough to ensure that the pea plant exhibits the phenotype associated with the dominant allele.
