Answer:
Positive natural selection.
Explanation:
The positive natural selection is a type of natural selection that increases the frequency of an allele or trait when it is advantageous for the population. What happened in the example is that the mouth with the slight change in morphology (trait) was more advantageous for the population in the south in relation to the ancestral morphology (still preserved in the population in the north), and therefore its frequency increased. This, in turn, is due to the fact that the food (prey) is not the same in the two habitats (north and south). The specific prey in the south, caused the new morphology to be selected, (increasing the frequency of individuals with the new mouth), becasue probably that trait allows the trouts in the south to hunt more effectively.

Elbow dysplasia is an inherited developmental abnormality that affects the elbow joint of dogs. It is accepted that the offspring of <span>a </span>dog<span> with the condition are likely </span><span>to develop the condition themselves. Therefore, the likely answer is: '</span>It has low diversity in its genes'. Even though the dog is a mixed breed, it is possible that one or both parents carried the gene for a predisposition to elbow dysplasia.

Explanation:
The best way to identify a mineral is the color of the mineral. The color of the minerals with different impurities is different. The pink color of the rose quartz and the gray color of the smoky quartz indicates that they contain different impurities. The impurities are the main factor behind the color of any mineral.
Hence, the correct answer is 'Color is the best way to identify a mineral'.
