20 gru 2023 · Genetic problems associated with inbreeding arise when closely related individuals are bred together, leading to a reduction in genetic diversity. This reduction in genetic diversity can result in an increased expression of detrimental genetic traits, such as inherited diseases or reduced fertility.
The European royal dynasties of the Early Modern Age provide a useful framework for human inbreeding research. In this article, consanguineous marriage, inbreeding depression and the purging of deleterious alleles within a consanguineous population ...
