Abstract
|
|
|
Selection for rapid and slow walking behavior in Drosophila melanogaster was carried
out for 17 generations by connected test-tube apparatus. Genetic divergence of the two
populations occurred within a few generations of selection. The realized heritability over
the first 10 generations of selections was approximately 2-3% for rapid and 6-13% for
slow population, respectively.
Correlated relationship between walking selection and other characters was analyzed
after few generations of selections. Deleterious effect of selection on low fecundity in
slow population and on short longevity in rapid population was found. These results
may be due to the favor in their physiological adaptability.
Males selected for slow walking showed reduction percentage of mating and mating
speed. The genes manifesting rapid walking behavior might be correlated with the
character of rapidity of copulation.
