General models for continued full-sib mating with two diallelic autosomal loci taking account of linkage, mutation and selection within and among lines are considered. The problems are first approached by deriving the full probability transition matr

A syndrome of associated aberrant traits is described in Drosophila melanogaster. Six of these traits, mutation, sterility, male recombination, transmission ratio distortion, chromosomal aberrations and local increases in female recombination, have p

Two-way selection for male recombination over seven intervals of the third chromosome in Drosophila melanogaster was practiced for nine generations followed by relaxed selection for five generations. Significant responses in both directions were obse

The distribution of the recombination fraction between two distal, autosomal loci, plexus and orange, was investigated in reciprocal crosses between the marker stock and each of two wild-type strains, Harwich and Ottawa. The dysgenic cross between Ha

The effect of lethal selection on linked marker loci was investigated in experimental populations of Drosophila melanogaster. Replicate experimental populations were initiated using flies heterozygous for the lethal gene Stubble and with the enzyme l

Summary Large reciprocal differences in spontaneous frequencies of recessive sex-linked lethals and female sterility were observed in the progeny of crosses between Cranston and Basc strains but lethal induction in non-hybrid parents was not markedly

Recombination fractions among four chromosome 3 enzyme loci were measured over a 20 generation period in experimental populations of Drosophila melanogaster. The experimental populations were initiated with complete pairwise linkage disequilibria amo

The dynamics of natural selection on a lethal fourth chromosome of Drosophila melanogaster was studied in replicated half-pint bottle and cage populations over 12 generations. Population numbers fluctuated widely in all populations, but there was no

The dynamic behavior of four-locus gametic frequency distributions was studied in five replicate cage populations of Drosophila melanogaster for up to 50 generations. The joint frequency distributions were resolved into gene freqcencies and various d
