Relative pre-adult viabilities of the three genotypes expressed in the F2 for 23 line crosses.

aMode of inheritance expressed in terms of the first listed allele, where rec = recessive, dom = dominant (both of which may be partial), and + = allele 1 favoured, - = allele 1 selected against, OD = overdominancebFirst part of sequential GE name is given when both alleles are from the same starch GE classcf = significant deviation from 1∶2∶1 in females only, m = in males only.Relative pre-adult viabilities of the three genotypes expressed in the F2 for 23 line crosses.
