Genocopy

Genocopy is a trait that is a phenotypic copy of a genetic trait but is caused by a different genotype. A genotype at one locus that produces a phenotype that at some levels of resolution is indistinguishable from that produced by another genotype; two types of elliptocytosis that are genocopies of each other, but are distinguished by the fact that one is linked to the Rh blood group locus and the other is not. The way to distinguish a recessive genocopy from a phenotype caused by a different allele would be by carrying out a test cross, breeding the two together, if they F1 hybrid segregates 1:2:1 then we can determine that it was a genocopy.
