Question:
Sex-linked characters are controlled by gene located primarily on
Sex-linked characters are controlled by gene located primarily on
Show Hint
Sex-linked traits are located on the X-chromosome and exhibit criss-cross inheritance; Y-linked traits are termed holandric.
Updated On: Sep 15, 2026
- X- chromosome
- Y-chromosome
- autosomes
- mitochondrial genome
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Sex linkage refers to the inheritance of genes located on sex chromosomes (allosomes).
Step 2: Detailed Explanation:
Sex-linked genes (X-linked genes, e.g., eye color in Drosophila, red-green color blindness and hemophilia in humans) are located on the non-homologous (differential) segment of the X-chromosome.
Because females possess two X chromosomes ($XX$) and males possess only one ($XY$), X-linked recessive traits exhibit characteristic criss-cross inheritance from father to daughter to grandson.
Step 3: Final Answer:
Therefore, sex-linked characters are controlled primarily by genes on the X-chromosome.
