✦ Synopsis

Gametic frequencies in five natural populations of D. subobscura were obtained by means of extracting wild chromosomes and subsequently analyzing them for inversions and allozymes. The results suggest that populations with a lower degree of chromosomal variation are genetically as variable as populations with a higher degree of chromosomal variation. morphic background; (2) whether the degree of heterozygosity of a certain chromosomal segment, chromosome or population is in positive correlation with the degree of heterokaryosis of this chromosomal segment, chromosome or population respectively; and finally (3) whether selection in marginal homokaryotypic populations is for specialized homozygous genotypes.

A number of experimental populations of Drosophila melanogaster either monochromosomal (e.g. isogenic) or polychromosomal (e.g. random heterozygous) with respect to their second chromosome were obtained by use of the L Cy/Pm marker strain. All populations were initially lethal free. Every other gene
