Criss-cross inheritance is the pattern where a parent of one generation passes a sex-linked character to the opposite sex in the next generation.
Types of Criss-cross Inheritance
- Diagenic: Father → Daughter → Grandson
- Diandric: Mother → Son → Granddaughter
Types of Non-criss-cross Inheritance
- Holandric: Father → Son → Grandson (Y-linked traits, e.g., Hypertrichosis, TDF)
