The statement that a fish is able to breathe outside of water but does not reproduce is not necessarily a disadvantageous mutation. It is important to consider the context and environmental factors in which this mutation occurs.
If the fish species lives in an environment with fluctuating water levels or occasional droughts, the ability to breathe outside of water could actually be advantageous. It would allow the fish to survive in temporarily waterless areas and potentially access new habitats or food sources. In such a situation, this mutation might increase the chances of survival and could be selected for by natural selection, hence impacting evolution.
However, if the fish lives in a stable aquatic habitat with no need to go out of water, this mutation might not provide any significant advantage and may not be beneficial for survival or reproduction. In such cases, if the fish does not reproduce, the mutation would not be passed on to the next generation and would not be inherited by other fish.
It's important to note that the impact of a mutation on evolution depends on various factors, including the environment, mating behaviors, and overall fitness of the organism. Mutations that increase the fitness and reproductive success of individuals are more likely to be passed on to future generations.

If a fish has a disadvantageous mutation, such as the inability to reproduce, it is less likely to be inherited by other fish. Disadvantageous mutations tend to decrease the fitness and reproductive success of individuals, which means they are less likely to pass on their genetic traits to future generations. Over time, this can lead to the mutation being eliminated from the population through natural selection.
In terms of the impact on evolution, the inability to reproduce can hinder the passing on of the mutation to subsequent generations and thus reduce its potential impact on the overall gene pool of the species. Therefore, it is less likely to have a significant impact on the evolutionary trajectory of the species. Other fish are also less likely to acquire this trait unless there are specific environmental conditions that make it advantageous for survival or reproductive success.
The scenario you presented involves a situation where a fish is able to breathe outside of water but does not reproduce. In evolutionary terms, whether this trait is advantageous or disadvantageous depends on the fish's environment and ecology. However, it is important to note that the inheritance and acquisition of traits in fish are primarily determined by the principles of evolution.
1. Disadvantageous mutation: If the ability to breathe outside of water hinders the fish's ability to survive, find food, or reproduce, then it can be considered a disadvantageous mutation. In this case, the fish with this trait might be at a reproductive disadvantage compared to other fish in the same population.
2. Inheritance of the trait: In order for a trait to be inherited, it needs to be passed on to offspring through genetic material (DNA). If the fish that can breathe outside of water does not reproduce, it is unlikely for this trait to be inherited by other fish in the population.
3. Impact on evolution: Evolution is the process by which genetic traits within a population change over time. Whether a trait impacts evolution depends on how it affects the fitness (survival and reproductive success) of individuals in a population. If the ability to breathe outside of water provides a significant survival advantage, fish with this trait may have a higher fitness, increasing the likelihood of it being seen in future generations. On the other hand, if it hampers survival or reproduction, it is less likely to impact the overall evolution of the population.
4. Acquisition of the trait: Acquiring a trait typically does not happen within a single individual's lifetime. Traits are typically acquired through genetic mechanisms, such as mutations, and then spread in a population over the course of generations. If the trait of breathing outside of water is not heritable, it is unlikely to be acquired by other fish in the population.
In summary, whether a trait is disadvantageous or advantageous depends on its impact on an organism's survival and reproduction. Traits are inherited through genetic mechanisms, and they can impact the evolution of a population over time. However, for a trait to be acquired by other individuals, it needs to be heritable and confer a fitness advantage.
