- A color mutation that decreases a bird's chances of sexual selection is beneficial in the sense that it prevent certain abnormalities in offspring like sexual dimorphism. Also sexual selection often proves to be a threat to the survival of the organisms as per handicap principle.
- A mutation in non coding region of DNA is harmful, as it is often observed to facilitate expression of wrong proteins at inappropriate places.
- A mutation in the that does not changes protein synthesis increased white pigmentation on a prey animal in snowy environment as it had prevented adaption of the prey and hence harmful for survival of it.
- A mutation decreasing plant's height in competition to light, makes them less exposed to sun energy important for photosynthesis and hence it is harmful for the plant.
Answer:
c, recesive

The answer to this question would be: vertebrae
In vertebrae fracture, traction is important to assure immobilization of the vertebrae. Movement can cause the fragment of bone in the fracture damaging the neural tissue in the vertebrae.
To ensure no movement in the neck, metal tongs can be put on the skull. The tongs will help fixate the skull with the shoulder.
