In February 1978, in Puerto Montt (Chile) the palearctic species Drosophila subobscura was detected. The expansion of the species in this country has been very rapid, and now it is found over a distance of at least 2000 km North-South. The newly established populations are very flourishing and show a high degree of inversion chromosomal polymorphism. On the(More)
Parthenocarpy is the development of the fruit in absence of pollination and/or fertilization. In tomato, parthenocarpy is considered as an attractive trait to solve the problems of fruit setting under unfavorable conditions. We studied the genetics of parthenocarpy in two different lines, IL5-1 and IVT-line 1, both carrying Solanum habrochaites chromosome(More)
Distances between populations ofDrosophila subobscura, based on differences in the frequencies of chromosomal arrangements have been estimated using data from about 65 populations. The distances have been calculated using the formula: $$D = \frac{1}{{2r}}{\text{ }}\sum\limits_{j = 1}^r {\sum\limits_{k = 1}^{Sj} {|p_{1jk} - } p_{2jk} |} {\text{ }},$$ wherer(More)
The effect of larval density on male mating success has been investigated with two strains of Drosophila melanogaster, a wild strain and a mutant strain, under low and high larval competition, and four different genotypic frequencies. The results show a strong sexual selection against mutant males when flies have been raised under low larval competition.(More)
The purpose of this study was to determine if different methods for average bioequivalence in high variability drugs coincide or not in their conclusions when applied to the same dataset, and to discuss the method validity and reliability of the conclusions. Different approaches for the evaluation of average bioequivalence were applied to the results of a(More)
