Based on this information, what is this plant's phenotype for the pea shape trait?

 - round peas
 - wrinkled peas
The pea plant's genotype for the pea shape gene is ee. The pea plant's genotype of ee has only e alleles. The e allele is for wrinkled peas. So, the pea plant's phenotype for the pea shape trait must be wrinkled peas.
To check this answer, consider whether the pea plant's alleles are dominant or recessive. The allele for round peas (E) is dominant over the allele for wrinkled peas (e). This means E is a dominant allele, and e is a recessive allele.
The pea plant's genotype of ee has only recessive alleles. An organism with only recessive alleles for a gene will have the recessive allele's version of the trait. So, the pea plant's phenotype for the pea shape trait must be wrinkled peas.
