Holandric traits are characteristics or traits determined by genes located on the Y chromosome.
Since the Y chromosome is passed almost exclusively from father to son, these traits are inherited in a male-specific pattern, passed down from fathers to their sons.
Holandric traits exhibit a unique inheritance pattern that is different from both autosomal and X-linked traits because they are exclusively linked to the Y chromosome.
Examples of holandric traits include male-specific disorders or characteristics determined by genes on the Y chromosome.
