High School Biology: Heredity
Heredity
Pedigree Analysis
- Characteristics determined by single genes are called Mendelian traits.
- Pedigrees depict family relationships and indicate which ones have a particular trait.
They can reveal the mode of inheritance of a particular trait.
- Autosomal dominant traits
- Autosomal recessive traits

Modes of Inheritance
Sex-linked Inheritance:
Y-linked inheritance (father to son)
Autosomal aneuploids:
In humans, autosomal aneuploidy often results in mental retardation because
do many genes contribute to brain function. Extra genetic material is apparently
less dangerous than missing material. (Sex chromosome aneuploidy is less severe
than autosomal aneuploidy.)
