Outbreeding effects in an inbreeding insect, Cimex lectularius
In some species, populations with few founding individuals can be resilient to extreme inbreeding. Inbreeding seems to be the norm in the common bed bug, Cimex lectularius, a flightless insect that, nevertheless, can reach large deme sizes and persist successfully. However, bed bugs can also be dispersed passively by humans, exposing inbred populations to gene flow from genetically distant popu...

متن کاملInbreeding and outbreeding depression in Caenorhabditis nematodes.
The nematode Caenorhabditis elegans reproduces primarily by self-fertilization of hermaphrodites, yet males are present at low frequencies in natural populations (androdioecy). The ancestral state of C. elegans was probably gonochorism (separate males and females), as in its relative C. remanei. Males may be maintained in C. elegans because outcrossed individuals escape inbreeding depression. T...
متن کاملTransposable elements in inbreeding and outbreeding populations.
Y OUNG et al. (1994) recently found that a putative transposable element (Lytl) is present at high abundance in the genomes of individuals sampled from a group of red-fruited species of Lycopersicon, and at a much lower abundance in green-fruited species of this genus. Similar or somewhat lower abundances were found in Solanum species believed to be closely related to Lycopersicon, and even low...
متن کاملThe Genetic Interpretation of Inbreeding Depression and Outbreeding Depression.
Inbreeding with close relatives and outbreeding with members of distant populations can both result in deleterious shifts in the means of fitness-related characters, most likely for very different reasons. Such processes often occur simultaneously and have important implications for the evolution of mating systems, dispersal strategies, and speciation. They are also relevant to the design of br...
