Both alleles contribute to the phenotype in a heterozygote. Example: blood groups A, B, AB.
Phenotype varies among individuals with the same genotype. Example: 2 patients with neurofibromatosis type 1 (NF1) may have varying disease severity.
Not all individuals with a mutant genotype will show the mutant phenotype. Example: BRCA1 gene mutations do not always result in breast or ovarian cancer.
One gene contributes to multiple phenotypic effects. Example: PKU causes many seemingly unrelated symptoms, ranging from mental retardation to hair/skin changes.
