    Introduction 5 Table 1.1 The six normal classes of segregation for a one factor difference in an ordered ascus, with illustrative data for the mating type locus of JVeurospora crassa (Lindegren, 1932) and the rubiginosa locus (r = a) of Bombardia lunata (Zickler, 1934). Segregation Table 1.2 The seven modes of normal segregation observed for two loci in ordered asci. The cross is AB x ab. Change of order between planes of first (I) and or second (II) division give rise to equivalent permutations. Note: The frequencies of the seven modes are given to a first approximation, neglecting double or more complex cross overs in all segments, in terms of the frequency of second division segregation of each locus, being x for Aa andj for Bb.
