Sex-linked Modes of Inheritance

Traits or conditions that are determined by genes located on sex chromosomes follow a sex-linked mode of inheritance. There are 3 sex-linked modes of inheritance: X-linked dominant, X-linked recessive, and Y-linked. In this scrollable interactive, you’ll examine pedigrees and explore the key characteristics that distinguish each of these inheritance patterns.
