You are studying wing colour in butterflies. You cross pure-breeding male butterflies that have blue wings with yellow eyespots, with pure-breeding female butterflies with orange wings and black eyespots. The F1 males all have orange wings and black eyespots, while the females have blue wings and yellow eye spots. You cross the F1 males and females and obtain the following F2 (the male and female F2 give the same ratios): 90 with orange wings and black eyespots 90 with blue...

Consider the following data on the lengths of 10 randomly selected pygmy blue butterflies in millimeters. 5.0, 3.9, 5.2, 5.5, 2.8, 6.1, 6.4, 2.6, 1.7, 4.3 Using R, can you conclude that median length of pygmy blue butterfly differs significantly from 3.7 mm. Use Wilkoxon signed rank test for a median to test your hypothesis at α = 0.05 level of significance. Marks distribution: 2 (hypothesis statement)+10(testing procedure)+2 (conclusion)

Groups of dolphins were observed off the coast of Iceland near Keflavik in 1998. The data in the file dolphin_dat on the course website give the time of the day and the main activity of the group, whether travelling quickly, feeding, or socializing. The dolphin groups varied in size. Usually feeding or socializing groups were larger than travelling groups.

Groups of dolphins were systematically observed off the coast of Iceland near Keflavik in 1998. Each observation included the main activity of a dolphin group (Activity) and the time of day the group was observed (Time). The groups varied in size, with feeding or socialising groups usually including more dolphins than travelling groups, but no information about group size was included with the data. The observations are summarised in the following table: No. of groups, summarised by activity and time....

In 1985, an assessment of a population of butterflies found that individuals appeared in a wide range of colors, from dark red to a light blue. In 2010, the same population of butterflies was assessed, and it was observed that only dark red and light blue butterflies remained. Identify the type of selection that occurred in this population and discuss how it supports the claim that a single environmental factor can yield a variety of phenotypic responses from different genotypes...
