In small populations, as long as children born with heritable birth defects die before they reproduce, the ultimate effect of inbreeding will be to decrease the frequency of defective genes in the population; over time the gene pool will be healthier. In larger populations, however, it is more likely that large numbers of carriers will survive and mate, leading to more constant rates of birth defects.
