Of metaphors and Darwinism: deconstructing genetic programming's chimera

Proceedings of the 1999 Congress on Evolutionary Computation-CEC99 (Cat. No. 99TH8406), 2003
This paper discusses several metaphors from Darwinism that have influenced the development of genetic programming (GP) theory. It specifically examines the historical lineage of these metaphors in evolutionary computation and their corresponding concepts in evolutionary biology and Darwinism.

Mouse Chimeras and Genetic Rescue of Mosaic Muscle

1990
The nuclear-cytoplasmic relationships existing within mosaic muscle will likely determine whether myoblast transfer can effectively rescue diseased muscle. The mouse chimera preparation is one source of such mosaic muscle in which that in vivo relationship can be investigated in the complete absence of complicating immunological or surgical trauma. For

Mangrove Genetics. IV. Postzygotic Mutations Fixed as Periclinal Chimeras

International Journal of Plant Sciences, 1996
Red mangrove (Rhizophora mangle) has shoot apices with a tunica-corpus organization; consequently somatic mutations are often manifested as complete or partial periclinal chimeras. Trees with branch systems exhibiting such chimeras for chlorophyll deficiency are rare in natural populations.

Chimeras vs Genetically Homogeneous Individuals: Potential Fitness Costs and Benefits

Oikos, 1992
Colonies of the compound tunicate Botryllus schlosseri show the capacity for colony specificity resulting either in vascular fusion or in rejection between genetically distinct colonies. Cosettlement of kin colonies increases the probability of fusion between allogeneic colonies.

Selection of genetically modified cell population using hapten-specific antibody/receptor chimera

Biochemical and Biophysical Research Communications, 2004
Efficient selection of the genetically modified cell population is a critical step to obtain the cells with desired properties. In this study, we propose an antigen-mediated genetically modified cell amplification (AMEGA) system employing an antibody/receptor chimera that triggers a growth signal in response to a non-toxic hapten dimer.

Genetic control of cell interactions in chimeras

Developmental Genetics, 1983
AbstractThe manufacture of mammalian chimeras by aggregating embryos of different genetic constitutions makes possible the study of the genetic control of cellular interactions during embryonic development. Several different chimeric combinations have been made to study the role of the sex‐reversed mutation in gonadogenesis and in gametogenesis.
