Variation and Mutations



This video defines a species, then explains why there is variation in sexually reproducing species. The video compares how variations caused by inheritance alone would look as a graph (discontinuous variation: bar chart), with how variation caused by both the genotype and the environment would look as a graph (continuous variation: bell shaped curve). The content on mutation is split into foundation and higher tier material. There is a synpotic link to enzymes.
