Question 4 (return to instructions after answering)
Similarly to the breakdown for body colouration, explain in 4 bullet points of 30 words or less each the 4 key ingredients for the evolution of female mate choice (hint: use what you learnt from computer practical 1).
Question 5
Looking at the graph you created, does the data collected from 30 female guppies in a dichotomous choice test support or refute the hypothesis that female mate choice is a key driver of the evolution and maintenance of bright body colouration in male guppies? Explain why in 70 words or less, also touching of why graphs are important but cannot give the provide a full representation of data.
Question 6
Using the concepts learnt in Computer practical 1, how could you test the hypothesis that female guppies that mate with colourful males will produces more numerous offspring that are better at foraging than offspring produced when mating with drab males? Keep in mind that females can mate many times during their life. Keep your answer to 150 words or less.

Question 9 (return to instructions after answering)
