A novel disease begins to infect individuals in a population. Is the population more likely to survive if it is genetically diverse or if the population has a similar genetic makeup?
A novel disease begins to infect individuals in a population. Is the population more likely to survive if it is genetically diverse or if the population has a similar genetic makeup?
A genetically diverse population of individuals is more likely to survive than a population of individuals with similar genetic makeup. Variation allows some individuals within a population to adapt to the changing environment and natural selection allows the expression of those beneficial traits to persist. For example, if a population of organisms has the same genetic makeup, it is far less likely to survive disease, drought, or predation than one with genetic variation.

Why is genetic variation important to a population?
Why is genetic variation important to a population?
The answer is "it allows a population to adapt in response to changing environments."
A genetically diverse population of individuals is more likely to survive than a population of individuals with similar genetic makeup.

Which of these processes is most important for genetic variation?
The answer is meiosis because that is where "crossover" and recombination of DNA take place in sexual reproduction, increasing genetic variation of offspring.

Imagine there are 3 populations of snow hares. Snow hares have different colored fur ranging from white to brown. White snow hares can hide from predators more easily in the snow, and light brown snow hares can hide more easily in the grass and brush when the snow melts. Which of these populations of snow hares is most likely to survive this a winter with constantly changing weather and unpredictable snow?
Population 1: All the snow hares are completely white
Population 2: Most of the snow hares are completely white, but some of them have brown splotches.
Population 3: There are many snow hares of all different colors from completely white to completely brown.
