Sex linked character have a distinct feature of

Options

A. Occurrence on X chromosome
B. Occurrence on Y- chromosome
C. Non criss cross inheritance
D. Criss cross inheritacne

Answer

**Step-by-Step Solution:**

1. **Definition of Sex-Linked Characters**:
- Sex-linked characters refer to traits or diseases that are associated with genes located on the sex chromosomes, primarily the X chromosome.

2. **Examples of Sex-Linked Traits**:
- Common examples of sex-linked traits include hemophilia and color blindness. These traits are often inherited in a specific manner due to their location on the X chromosome.

3. **Inheritance Patterns**:
- Sex-linked traits are typically recessive. This means that for a male (who has only one X chromosome) to express a recessive trait, he only needs one copy of the allele. In contrast, females (who have two X chromosomes) need two copies of the recessive allele to express the trait.

4. **Crisscross Inheritance**:
- Crisscross inheritance is a pattern observed in sex-linked traits. It describes how traits can be passed from a grandfather to a granddaughter through the daughter. For example, if a grandfather has a recessive trait on his X chromosome, he can pass it to his daughter (the mother), who may then pass it to her son or daughter.

5. **Conclusion**:
- The distinct features of sex-linked characters are that they are located on the X chromosome, they often exhibit crisscross inheritance, and they are typically recessive in nature.
