What is an example of a populations with organisms?

Does having a dominant allele mean that it will be found in greater frequency in the population?  Explain

Imagine a population of crabs living on a white sandy beach. The crabs ONLY occur in two color - red and blue, each controlled by color genes. Over time, will the crab population shift toward white? Why or why not?

Mention the attributes which a population has but not an individual organism.

If '+' sign is assigned to beneficial interaction, '-' sign to detrimental and '0' sign to neutral interaction, then the population interaction represented by '+' '-' refers to what?

A population of 1,000 wild turkeys is studied and observed by scientists on an island. The scientists construct a study over five years to observe the temperature, amount of precipitation, the daily value of berries individually consumed that were their exclusive food source, mating patterns, and available habitat for nesting. The scientists determined that as the climate changed, the population began to decrease. Using the Hardy-Weinberg Equilibrium as a null hypothesis, which statement would support the alternative hypothesis? No change in the allele frequency of the population was observed because the population size is large. A change in the allele frequency of the population was observed because natural selection occurred due to the change in climate. No change in the allele frequency of the population was observed because mutations will not occur as a result of climate change. A change in the allele frequency of the population was observed because mating is random.
