    CHAPTER XI SYMBOLS AND FORMULAE Symbols a number observed in a class. A ± sum of a 1 and a 4 in a four-class segregation. A 2 sum of «2 and a 3 in a four-class segregation. D x deviation from zero of maximum likelihood expression of x. f reclassification due to incomplete manifestation of a character. i x = — = ^r- amount of information concerning x 71 V x per individual in a family. k coefficient in orthogonal functions. I the characteristic proportion in a two-class segregation which may be represented as 1: 1. m proportion expected in any class. n number of individuals in a family. p recombination fraction. P — p 2 or (1 — p) 2 in F 2 data. s x standard error of x (a x = s x when x is fixed by hypothesis). S summation over all classes. V x variance of x — {s x ) 2 = —. Tti/X x (i) 1 — y = chance of any individual being of a chosen type in a two-class segregation, (ii) Also used as p(l — p) in human data. 121
