Based on this information, what is Malia's phenotype for the Thomsen disease trait?

 - not having Thomsen disease
 - having Thomsen disease
You need to determine Malia's phenotype for the Thomsen disease trait. First, consider the alleles in Malia's genotype for the Thomsen disease gene. Then, decide whether these alleles are dominant or recessive.
The allele for having Thomsen disease (M) is dominant over the allele for not having Thomsen disease (m). This means M is a dominant allele, and m is a recessive allele.
Malia's genotype of Mm has one dominant allele and one recessive allele. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, Malia's phenotype for the Thomsen disease trait must be having Thomsen disease.
