Vedclass · Answer

(A) The $cis-trans$ test (or complementation test) is used to determine if two mutations are in the same gene or different genes.If two mutations are in the same gene,they will show a mutant phenotype in the $trans$ configuration (complementation does not occur).If two mutations are in different genes,they will show a wild-type phenotype in the $trans$ configuration (complementation occurs).However,if two genetic loci produce identical phenotypes in both $cis$ and $trans$ configurations,it indicates that the mutations are not affecting the same functional unit in a way that prevents complementation,or they are effectively acting as independent units. In the context of classical genetics,when mutations at two closely linked loci show identical phenotypes and do not exhibit the expected $cis-trans$ effect,they are often referred to as Pseudoalleles.
