principle 2: Overproduction and the struggle to survive
Principle 3: Differential survival and reproduction (survival of the fittest)
Genetic variation within the mice population shows tan mice have a higher fitness because of the advantage of camouflaging from the birds and the population grows by the tan genetic variation.
Principle 4: Change in the gene pool
there is over production of the mice because of the white and black mice getting eaten by the crow. the tan mice are more likely to survive and reproduce and pass their genes because of the characteristics color to match the sand and stay away from predators .
Mice who are tan are able to camouflauge to the sand than the white and black mice ,the tan mice are more likely to survive and reproduce to the environment and reproduce that means tan mice are going to be more populated then green because of the color characteristics.
Over time the population of the tan mice color trait is passed down on to future generations to make a gene pool. over time the gene pool population will be tan because of the genes being passed down.
