- The likelihoods of getting exactly the ratio
*AA*: *Aa* as reported by Mendel were calculated as described by eq. 1 except that the value 100 is replaced by the number of segregants, given in the column “total”, and using the Excel function BINOM.DIST. The likelihoods (*L*_{m}) are listed in the columns “Likelihood from binomial assuming:” in which the two columns correspond to different expectations; the 1: 2 ratio, and Fisher’s ratio. The columns under “In 9 trials” give the corresponding likelihoods in a series of nine trials, there being nine categories in these data, this is estimated as [1 - (1 - *L*_{m})^{9}]
- The shaded values (i) are the case in the most abundant class (
*Rr Ii*, 127 plants) where there are fewer *Aa* plants than Fisher’s ratio predicts (78 vs 84.67), and (ii) the lowest likelihood of the nine *AA*: *Aa* segregation ratios (1.6% for the *RR Ii* class of 60 plants)
