cis configuration

[sis]
1 the presence of the dominant alleles of two or more pairs of genes on one chromosome and the recessive alleles on the homologous chromosome.
2 the presence of the mutant genes of a pair of pseudoalleles on one chromosome and the wild-type genes on the homologous chromosome. Compare coupling, trans configuration.
3 (in chemistry) a form of geometric or stereoisomerism in which two substituent groups are on the same side of a double bond or aliphatic ring. Also known as Z (zusammen) configuration. also called cis arrangement, cis position.

cis configuration
