Page 2: Autosomal and X-Linked Dominant Inheritance
This page details three major inheritance patterns: autosomal dominanter erbgang (autosomal dominant), autosomal recessive, and X-linked dominant inheritance.
Example: Autosomal dominant conditions include Huntington's disease, Marfan syndrome, neurofibromatosis, and polydactyly.
Highlight: Key characteristics of autosomal dominant inheritance:
- Trait appears in every generation
- Males and females equally affected
- Affected child has at least one affected parent
Definition: In autosomal recessive inheritance, both recessive alleles must be present (homozygous aa) for trait expression, while carriers have a heterozygous genotype (Aa).
