Niet alle individuen met een mutant genotype zal tonen het mutant fenotype. Voorbeeld: BRCA1 genmutaties niet altijd resulteren in borst- of eierstokkanker.
One gene contributes to multiple phenotypic effects. Example: PKU causes many seemingly unrelated symptoms, ranging from mental retardation to hair/skin changes.
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.
Phenotype varies among individuals with the same genotype. Example: 2 patients with neurofibromatosis type 1 (NF1) may have varying disease severity.
Both alleles contribute to the phenotype in a heterozygote. Example: blood groups A, B, AB.
Fluorescent DNA or RNA probe binds to specific gene site of interest on chromosomes. Used for specific localization of genes and direct visualization of anomalies (e.g., microdeletions) at molecular ...
