Storyboard Text

  • There is a population of rabbits starts with only one type of allele (100%) , which means right now all of them have no differences, they are all the same.
  • Then suddenly, a mutation happens to the rabbit population, which causes one of the rabbits to change a color, and it looks different to the other rabbits, which is genetic variation.
  • The mice over produce so their offspring will get the allele that lets them blend in with dark environments, but since a mutation happened, the one rabbit that got mutated now stands out and attracts predators to eat it.
  • However, there can be an environment change so this will allow the mutated mouse to be better fit for the environment and camouflage. This will give the other dark color mouses a disadvantage . So, this will allow the mutated mouse reach the reproductive age.
  • So, because the original allele for the rabbits were dark colored, this now makes them spotted easily by predators, which makes them weak.
  • Now, since the mice with the original alleles are now slowly dying or fading away, now the mice that are mutated has a better chance in surviving the population because now they blend in .
