Web(i) Write down the transition probabilities of the Markov chain thus deﬁned. (ii) Assume that we start with a hybrid rabbit. Let µn be the probability dis-tribution of the character of the rabbit of the n-th generation. In other words, µn(GG),µn(Gg),µn(gg) are the probabilities that the n-th generation rabbit is GG, Gg, or gg, respectively. WebProbabilities can be written as fractions, decimals or percentages on a scale from 0 to 1.
