The risk of a child developing an autosomal recessive disorder increases with inbreeding. Carriers of a recessive disorder may be unaware they possess a mutated gene because two copies of a recessive allele are needed for gene expression. On the other hand, autosomal dominant disorders are seen in the parents … See more When two closely related organisms mate, their offspring have a higher level of homozygosity: in other words, an increased chance that the offspring will receive identical … See more Successive inbreeding of animals has been used to establish "pure" lines for scientific research.
