* Wrinkled Seed: This means the plant has at least one copy of the recessive allele for wrinkled seeds. We'll represent the wrinkled allele with "w" and the dominant smooth allele with "W". Since it's heterozygous, it has one of each: Ww

* Red Flower: We need to know if red flowers are dominant or recessive. Let's assume red flowers are dominant. We'll represent the dominant red allele with "R" and the recessive (let's say white) allele with "r".

Possible Genotypes:

* If red is dominant: The plant could be either Rr (heterozygous) or RR (homozygous dominant) for flower color.

Therefore, the complete genotype of the plant could be one of the following:

* WwRr (Heterozygous for both seed shape and flower color)

* WwRR (Heterozygous for seed shape and homozygous dominant for flower color)

Important Note: To know the exact genotype, you'd need more information about the parents or the offspring of this plant.
