The genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele. If both dominant alleles are present in a genotype (homozygous dominant) then the phenotype is "A" phenotype. If one dominant allele and one recessive allele are present (heterozygous dominant) then the phenotype is "A". Finally, if both recessive alleles "a" are present (homozygous recessive) then the phenotype is "a". Therefore, the answer to your question is the genotype AA would result in an "A" phenotype because the genotype is homozygous dominant.
single genes wiht multiple alleles
For a dominant trait to be expressed, you either need a RR or an Rr genotype. The other genotype, rr, is recessive only. In genetics, capital letters represent a dominant allele, and lower case letters represent the recessive allele.
Phenotype. Allele and genotype both describe genes wheras phenotype describes outward appearance.
The allele pair of someone with a genotype TT is homozygous dominant.

If A represents a dominant allele, then the AA genotype would produce the dominant phenotype.

The allele pair of someone with a genotype TT is homozygous dominant.
Having one allele for tall stems and one allele for short stems is a heterozygous genotype and could be represented as Tt, where T represents the tall allele, and t represents the short allele, if the tall allele has complete dominance over the short allele.
Genotype
The allele pair of someone with a genotype TT is homozygous dominant.
A genotype in which there are both a dominant and a recessive allele is called heterozygous.
