Question

What do you mean by sex-linked characters? Describe with the help of line sketches, the inheritance of two sex-linked characters in humans.

Hint:

Remember: Sex-linked traits are carried on sex chromosomes, and disorders like hemophilia and color blindness are more common in males due to their single X chromosome.

Answer 1

Sex-linked characters are traits that are associated with genes located on the sex chromosomes (X or Y). They are inherited differently in males and females. 
Examples of sex-linked inheritance: 
Hemophilia: A disorder where blood does not clot properly. 
Color blindness: An inability to distinguish certain colors, typically red and green.
