WebAlleles may be arranged in two ways, viz., cis position and trans position (Fig. 13.1). When two wild alleles are located in one chromosome and their mutant alleles in homologous chromosomes (++/ab), it is known as cis-arrangement. Thus, in cis position alleles are linked in coupling phase. WebGenes in coupling configuration produce more wild-type gametes; genes in repulsion produce fewer wild-type gametes. true Assume that you wish to determine if two genes are linked or not.

"WebIn case of coupling phase, there is linkage either between dominant genes (AB) or between recessive genes (ab). The repulsion phase refers to linkage between dominant and recessive genes (Ab/aB). High frequency of coupling phase (AB/ab) causes an upward bias in the estimates of additive and dominance variances. " - Coupling genetics definition
