Genetic Diversity And Adaptation Flashcards
Describe genetic diversity
The total number of different alleles in a population
When is genetic diversity reduced?
When a species has fewer different alleles
How were Darwin’s Galapagos finches an example of adaptation?
Each had a different beak shape based on the primary source of food on the island they were on
How can a random allele mutation increase chances of survival?
Individuals will be better adapted to their environment
How will the mutated individuals pass on their traits?
Successful reproduction
What will happen when the population with the advantageous allele reproduce?
Those without it will become a minority
How did the peppered moth population change during the industrial revolution?
The trees were blackened so black peppered moths (mutation) became more common than the white variety that camouflaged with the lichen before
