A different form of a gene
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. Since females have two X chromosomes, the presence of a mutation in a single one of them does not normally result in color blindness. 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.
The proprioceptors
The proprioceptors such as muscle
spindle and golgi tendon organ are sensors located in the limbs. The proprioceptors
give information about muscle length, muscle tension and joint angle which is coordinated
to provide information about the limb’s position in space.
