What I liked about this lesson most of all was the helpful videos and examples inside the powerpoint. I found the Hardy-Weinberg law very interesting.
What I liked about this lesson the most was that many evolution’s started with mutations in the individuals that introduced many different alleles in just one population and the sexual reproduction can also quickly spread a mutation through a population.
