RELEASE OF GENETIC VARIABILITY THROUGH RECOMBINATION. V. BREAKUP OF SYNTHETIC LETHAIS BY CROSSING OVER IN DROSOPHILA PSEUDOOBSCURA

Technical Report ·
OSTI ID:4070919
Results are reported from a series of studies on the mechanisms that maintain genetic diversity in Mendelian populations in which three species of Drosophila were used. Samples of chromosomes taken from the natural populations were tested for viability effects in homozygous conditions. From these samples 20 chromosomes were selected in each species, and the strains containing the 20 selected chromosomes were intercrossed in all possible combinations. A total of 1900 recombination chromosomes per species resulted, which were then tested for their viability effects in the homozygous condition. The viability of the homozygotes for the recombination chromosomes varied all the way from normal and subvital to semilethal and complete lethality. Data are tabulated and discussed. (C.H.)
