Answer
⚠️ Sex linked genes are present on option (D) non homologous region of X chromosome ✔️✔️
Answer:
Sex-linked genes are present in Non-homologous region of the X chromosome.
Sex-linked genes can be either X linked or Y linked.
In the case of X linked disorders: Men usually have one X and one Y chromosome, hence, if they inherit any diseases allele on the X chromosome, it is expressed.
On the other hand, women can be both carriers as well as diseased.
In the case of Y linked disorders: Since the Y chromosome is only present in males, hence, any diseased Y chromosome only affects males.
