Answer:
A mutation is generally referred to as certain alternations in the gene whether it may be DNA sequences, which may be beneficial, harmful or of no significance to the mutant gene bearing organisms.
Explanation:
- A mutation that increases the ability to store moisture in a dry environment is obviously beneficial. Because it prevents dehydration and maintains normal functioning in spite of adverse conditions.
- 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.
A mutation can be defined as the alteration in the single base pair of the DNA. It can be harmful, neutral or beneficial for the organism in which it takes.
Explanation:
Beneficial:
A mutation in the organism that increases its ability to store moisture in a dry condition will prevent the organism from drying out in the extreme conditions.
A color mutation that will increase the chances of sexual selection in the birds is beneficial it can prevent the sexual dimorphism in the offspring produced by the birds.
Harmful:
A mutation in a non coding region is harmful as it can lead to the expression of faulty proteins at inappropriate place.
A mutation in the plant which decreases the plant's ability to grow and gives plant a short height will be harmful because there will be more competition for sunlight.
The mutation that does not changes the protein synthesis but increases white pigmentation on a prey in a snowy environment as it has prevented adaption of the prey and thus this mutation is harmful.
