Match each classic genetic principle to its defining clinical or pathophysiological description.
- A genetic disorder presents at an earlier age of onset and with more severe symptoms in successive generations of a family.Anticipation
- A single gene mutation causes multiple diverse phenotypic traits across different organ systems, such as simultaneous ocular, cardiovascular, and skeletal abnormalities.Pleiotropy
- The clinical expression of a disease differs significantly based on whether the responsible mutant allele was inherited from the maternal or paternal parent.Genomic imprinting
- Pathogenic mutations in entirely different genes located on different chromosomes result in the exact same clinical disease presentation.Locus heterogeneity
Cevap
Anticipation matches with increasing disease severity in successive generations. Pleiotropy matches with a single mutation causing diverse multi-organ traits. Genomic imprinting matches with parent-of-origin dependent disease expression. Locus heterogeneity matches with distinct gene mutations yielding identical clinical presentations.
Each definition precisely describes a foundational genetic mechanism essential for interpreting clinical genetic presentations and pedigree charts in practice. Proper alignment matches anticipation with generational severity, pleiotropy with multi-organ effects, imprinting with parent-of-origin expression, and locus heterogeneity with distinct loci causing identical phenotypes.
