Extract

There is considerable research efforts aimed towards detecting disease resistance genes or QTL. If found and used in breeding programmes, such genes should reduce the likelihood and severity of epidemics. A critical question is which genes should be used and what will their impact be? Genetic epidemiological modeling techniques (MacKenzie and Bishop, 2001) can give insights into how we should prioritise the prospective resistance traits, hence candidate genes or QTL corresponding to these traits, for specific diseases. Here, a stochastic genetic epidemiological model is used to investigate the relative importance of different genetic control options and the effect of host genetic heterogeneity in controlling the transmission of a microparasitic, e.g. viral or bacterial, infection.
