Storyboard Text

  • Genetic Variation
  • Overproduction and struggle to survive
  • Differential survival and reproduction
  • There is a population of snakes with different skin color  -yellow snakes -green/brown snakes
  • Changes in Gene Pool
  • Less than half the snakes born will survive and the yellow snakes which are visible to predators will start to die out. 
  • 
  • The green/brown skin snake has a higher survival rate and is most likely to reproduce offspring and pass on its trait to future generations.
  • 
  • The change in the gene pool is that the population of yellow skin snakes started to decrease and the population of green/brown skin snakes started to increase which meant they survived and reproduced more.
