A genetic chimerism or chimera (/ k aɪ ˈ m ɪər ə / ky-MEER-ə or / k ɪ ˈ m ɪər ə / kim-EER-ə) is a single organism composed of cells with more than one distinct genotype. Animal chimeras can be produced by the fusion of two (or more) embryos .
As the figure shows, each time that the mouse with the desired trait (in this case the lack of a gene (i.e. a knockout), indicated by the presence of a positive selectable marker) is crossed with a mouse of a constant genetic background, the average percentage of the genetic material of the offspring that is derived from that constant ...

The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child. There are over 6,000 known genetic disorders in humans.

The kind of technology used in genetic engineering is also being developed to treat people with genetic disorders in an experimental medical technique called gene therapy. [23] However, here the new, properly working gene is put in targeted cells, not altering the chance of future children inheriting the disease causing alleles.
Transduction This is an illustration of the difference between generalized transduction, which is the process of transferring any bacterial gene to a second bacterium through a bacteriophage and specialized transduction, which is the process of moving restricted bacterial genes to a recipient bacterium.
