Red flower color is dominant because it is represented by the allele "F." Orange flower color is recessive and is represented by the allele "f."
If the the trait is controlled by only one allele and the allele is completely dominant then once inherited the offspring with exhibit that phenotype
Tt or TT

Some autosomal disorders in humans that are controlled by dominant alleles include Huntington's disease, Marfan syndrome, and neurofibromatosis type 1. These disorders are expressed when an individual inherits a single copy of the mutated gene from one parent.
Waardenburg syndrome is typically inherited in an autosomal dominant pattern, meaning that only one copy of the mutated gene is needed to develop the condition. However, there are rare cases where it can be inherited in an autosomal recessive pattern, requiring two copies of the mutated gene.
