WebFor genes in coupling configuration, two wild-type alleles are on the same chromosome and the two mutant alleles are on the homologous chromosome. For genes in repulsion, the wild-type allele of one gene and the mutant allele of the other gene are on the same chromosome and vice versa on the homologous chromosome. WebCoupling (C) or cis configuration: the two dominant alleles are on one chromosome and the two recessive alleles are on the other chromosome (GroRo groro and groRo Groro) Repulsion (R) or trans configuration: each chromosome contains one dominant allele and one recessive allele (Groro RoGro and groRo RoGro) jena iannucci

WebWhen both nonallelic mutants are present on one homolog and the other homologous chromosome carries the plus alleles (a b/++), the genes are said to be in the coupling configuration. The repulsion configuration refers to a situation in which each homolog contains a mutant and a wild-type gene (a+/+ b). See cis-trans configurations.
