Journal of Theoretical Biology. It is worth noting here that the male-only release of systems with weakly suppressed lethals does not appear able to produce the region in which lasting introgression occurs within both populations. Maynard Smith J, Slatkin M.
We now investigate the effects of each parameter on the overall equilibrium population size by considering variations in each while the other three are held constant—at the base values detailed in Table 2. A second possibility black regions in Fig 8 is that the UD system achieves lasting and near-fixation transgene introgression in both the target and non-target populations.
It took place in March at the Institute of Obstetrics and Gynaecology in London and was attended by obstetricians, paediatricians, geneticists, midwives and ultrasonographers from the North West Thames Health Region. Ecological parameters influence the size of a mosquito population in absence of any control measures.
Qualitative theory of the spread of a new gene into a resident population. A spectacular example of variability between closely related species is the muntjacwhich was investigated by Kurt Benirschke and Doris Wurster.
The first licensed dengue vaccine: An important tool for integrated preventive strategies against dengue virus infection.
It refers to the scenario whereby individuals heterozygous at a given genetic locus are less fit than either of the homozygote states and is the inverse of the better known hybrid vigour. Retrieved 22 April In order to explore these effects we simulate a introduced:wild release of each gene drive system.
Genetic control of mosquitoes. After [ 36 ], a schematic representation of the two-deme model. However, in spite of the fact that KR is inherently self-limiting, the same regulatory questions are still likely to need addressing. These allow desirable genetic traits such as a much reduced capacity for vectors to transmit viruses to be spread through a target population; taking advantage of natural mate seeking behaviour to locate vector sub-populations that can be extremely difficult for humans to locate and reach.
