Imagine that we are studying the colour coat of a population ofchamoix in the Alps. There are two morphs, white and dark brown,which we know to be genetically determined.
(a) We observe that the frequency of brown decreased quitesubstantially between 2010 and 2011. Give 4 different potentialexplanations for this decrease
(b) Imagine that we observe that the frequency of brown varieserratically over the next 4 years. Give two potential explanationsfor the changes in the frequency of brown
