Cytoplasmic incompatibility and mating preference in Colombian Drosophila pseudoobscura.
MACRAE and ANDERSON observed a large frequency change of mitochondrial DNA (mtDNA) haplotypes in a population initiated with two allopatric strains of Drosophila pseudoobscura, BogER from Colombia and AH162 from California. They concluded that mtDNA haplotypes in D. pseudoobscura are not always selectively neutral. NIGRO and PROUT suggested, however, that a maternally transmitted incompatibilit...
متن کاملMitochondrial gene divergence of Colombian Drosophila pseudoobscura.
Isolated populations of drosophila pseudoobscura, separated from North American populations by about 2,400 km, were found in Colombia in 1960. We compared for sequences of the small ribosomal RNA (srRNA) gene on the mitochondria between North American and Colombian D. pseudoobscura in order to clarify the age of the Colombian isolates. The North American populations were not genetically differe...
متن کاملMating Control by Gene Arrangements in DROSOPHILA PSEUDOOBSCURA.
ITH a positive correlation between mating speed of homokaryotypes and the Wf requency of gene arrangements from the Mather, California, population of Drosophila pseudoobscura, it became clear that gene complexes included in those arrangements must play a prominent role in courtship behavior, a role essential to fitness in natural populations (SPIES and LANGER 1964a). In its sibling species, D. ...
متن کاملChromosomal control of mating activity in Drosophila pseudoobscura.
Lines containing two third-chromosome inversions (Arrowhead and Pikes Peak) of Drosophila pseudoobscura selected for fast and slow mating speed were crossed to a multichromosomal, dominant marker inversion stock, and strains with various combinations of chromosomal derivation were tested for their mating activity. When lines were selected isodirectionally with the known third-chromosome control...
متن کاملAge-Dependent Male Mating Investment in Drosophila pseudoobscura
Male mating investment can strongly influence fitness gained from a mating. Yet, male mating investment often changes with age. Life history theory predicts that mating investment should increase with age, and males should become less discriminatory about their mate as they age. Understanding age-dependent changes in male behavior and their effects on fitness is important for understanding how ...
