Document Summary
Overproduction: you need to produce more o spring than you would ever need. Variation: the many o spring that get produced, are all di erent, mixture of parents dna. Heritable variations: helps the species stay diversi ed. Consequence for variation: only the ones best suited for their environment survive. Only 5/100 make it through the rst 8 hours. They all hatch at the exact same time, which helps the most amount to make it to the water. Change in genetic composition due to mate choices or competition for mates. The males ability to out rival other males. Gd is reduction in the variation by random events. 50% red 50% blue > tornado > 42% red 58% blue. Mainland: 50% red 50% blue, founder: 29% red 71% blue. Whoever goes out to the island is just because, therefore its random. Before: 27% red 73% blue mainland, island before 100% red 0% blue. They go back and forth from the island.
