Transmission of Sex-Linked Character to Opposite Sex
Parents of one-generation pass the sex-linked character to the opposite sex in the next generation is known as:
- Sex-limited inheritance
- Criss-cross inheritance — Correct Answer
- Sex-influenced inheritance
- Hologenic inheritance
Explanation:
Correct Answer: Criss-cross inheritance
When a parent of one generation passes a sex-linked character to the opposite sex in the next generation, it is called Criss-cross inheritance.
Types of Criss-Cross Inheritance
| Type | Pattern |
|---|---|
| Diagenic | Father → Daughter → Grandson |
| Diandric | Mother → Son → Granddaughter |
Non-Criss-Cross (Same Sex) Inheritance
| Type | Pattern |
|---|---|
| Holandric | Father → Son → Grandson (Y-linked) |
| Hologenic | Mother → Daughter → Granddaughter (W-linked in birds) |
Why Other Options Are Wrong
- Sex-limited inheritance: Traits expressed only in one sex (e.g., milk production), but genes are on autosomes — no cross-sex transmission pattern.
- Sex-influenced inheritance: Autosomal genes whose expression differs between sexes due to hormonal environment.
- Hologenic inheritance: A type of non-criss-cross; passes from mother to daughter only.
