Methods in Human Genetics
Single-Gene Inheritance: Most human genetic disorders are determined by recessive alleles.
A few human genetic disorders are determined by dominant alleles.
Many human traits are either sex-linked or sex-influenced.

Complex Inheritance
Many human traits are influenced by many genes.
The environment influences the expression of genes.

Chromosomal Inheritance
Some genetic disorders are caused by abnormal numbers of sex chromosomes.
In humans, the Y chromosome determines maleness.
Some genetic disorders are caused by abnormal numbers of autosomes.
