Analysis of the Effect of Slow versus Rapid Inbreeding Accumulation on Quantitative Traits of Animal Population
Abstract
Inbreeding and its consequences have long been a concern of medicine, animal and plant breeding, evolutionary biology and conservation. The main effect of inbreeding on quantitative traits is the reduction mean of size, fertility, vigour, yield and fitness. Dominance and overdominance hypothesis are two genetic mechanisms that have been proposed as the cause of inbreeding depression. Both relate to the decrease in heterozygosity during the inbreeding process. There is research showing that inbreeding depression was lower in population accumulating inbreeding at a slow rate than in populations with more rapid rates of inbreeding, presumably because of the greater opportunity for selection to act. Yet data on the inbreeding accumulation rate on quantitative traits in animal population are few. Therefore, the objective of this project is to study the effects of slow versus rapid inbreeding accumulation on quantitative traits under random and phenotypic truncated selection. To reach this aim we use computer modelling and analyse real data based on pedigree information of several animal species such as horse, dairy cattle, mouse and tribolium. The simulation is performed by a combination of FORTRAN90 and SAS programs.
