Genetic linkage - Wikipedia

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. WebWhen two or more characters of parents are transmitted to the offsprings of few generations such as F 1, F 2, F 3 etc. without any recombination, they are called as the linked characters and the phenomenon is called as linkage. This is a deviation from the Mendelian principle of independent assortment. thunder bay enterprise car rental
