Fish hatcheries in the mountain states are hoping to begin a breeding program that combines the best features of two fish varieties to create a super fish; one that could withstand the extremes in water temperatures as well as water pH. Scientists want to find a fish that they can breed with brown trout, a hardy fish that can withstand many adverse environmental conditions. Based on the DNA profiles of the four trout varieties, which fish would be the best choice for the breeding program? A)Brook trout B)Golden trout C)Rainbow trout D)None of the three as they are different species.

Answer:
D)None of the three. All the three varieties of fish are quite different to each other and therefore their DNA traits will also be different. Hence, they cannot be combined with each other easily for making a super fish. It is very important to have similar DNA traits for mutation to occur. Different types of DNA traits in organisms may not easily match up with each other and may even create problems if they are mixed together.
