GENETICS OF NATURAL POPULATIONS. XXIX. IS THE GENETIC LOAD IN DROSOPHILA PSEUDOOBSCURA A MUTATIONAL OR A BALANCED LOAD

Technical Report ·
OSTI ID:4075618
The mutational component of a genetic load consists of genetic variants and a balanced component. The genetic variants reduce the fitness of their homozygous, or of both homozygous and heterozygous carriers, in most environments. The balanced component of the load consists of heterotic genes and gene complexes, which yield highly fit heterozygotes but relatively less well adapted homozygotes. Balanced loads are maintained primarily by natural selection. The role of the genetic load was studied in populations of Drosophila pseudoobscura. Data are tabulated and discussed. (C.H.)
