MATING SPEED CONTROL BY GENE ARRANGEMENT CARRIERS IN DROSOPHILA PERSIMILIS

摘要: Genotypes which control mating behavior must have a vital function in the dynamics of natural populations, especially gearing sexes for reproductive efficiency and high Darwinian fitness. Drosophila persimilis from locality Yosemite region California (White Wolf at 8,000 ft elevation) displays propensity differences controlled some degree by Whitney Klamath arrangements chromosome III (Spiess Langer, 1961). Mating chromosomal complexes may contribute substantially to fitness populations. The complete elaboration these is essential understanding what "selection has been aiming at" both artificial or more properly how genotypes responded environmental stimuli order maintain It most important first understand genic populations before we can be position interpret their nature. When WT KL homokaryotype flies were given multiple choice 24 hours, males consistently inseminated twice as many females males. also than females, though tests not significantly so. Since 24-hour did inform us details left unanswered questions rate within that time, decided observe over short period detail. A efficient technique was needed carry out complex matings with two karyotypes same chamber. following arose: Which sex final proportion matings? How much result actually took place immediately?
