In a study of a species of deer, researchers measured body mass (kg) and recorded coat colour (either light brown or dark brown) in two populations: one from a lowland area and one from a highland area.
(a) Describe the difference between continuous variation and discontinuous variation, using body mass and coat colour as examples. In your answer, state the genetic basis of each type.
(b) The researchers want to compare the mean body mass of the two populations. Describe how a t-test could be used to analyse these data.
