Inbred mutations
WebInbred strains of mice that fail to adapt to the new conditions for reinforcement may provide a model for the insistence on sameness characteristic of the autism phenotype.

WebAug 24, 2010 · As a whole, mutation is a powerful source of allogenicity in inbred strains. Single mutations with large phenotypic effects in inbred strains of mice provided the first evidence of their vulnerability to mutation (Lord and Gates, Reference Lord and Gates 1929; Yoo, Reference Yoo 1980) and, controversially, they have been a major source of new ...
WebSince inbreeding increases the probability of being homozygous, it increases the fraction of the potential deleterious effect that is expressed and, therefore, exposed to selection. This causes some increase in the selective pressure against (partially) recessive deleterious alleles, which is known as purging.
