Answer: B (Color blindness)

Explanation:

Typical red-green color blindness in human patients is caused by mutations on genes located in the X chromosome. These mutations act in a recessive manner.

Males, in contrast, have a single X chromosome and therefore the presence of a mutation is likely to cause the disease.

About the other options: Down‘s syndrome is a numerical chromosomal anomaly, not related to sex. Human blood type is a codominant trait. Finally, tail length in dogs is a polygenic trait not amenable to classic Mendelian analysis.
