  • Standard errors of the estimates are given in parentheses. The length variant frequency distributions are significantly different between generations 5 and 50 (see text), although none of the residual values for any of the length variants were < −2 or >2. The number of lines at generation 5 is 39 and the number of lines at generations ∼50 and ∼90 is 33.
