The document discusses the complementation test, also known as the cis-trans test, which is used to determine if two mutations causing a specific phenotype are alleles of the same gene or variations of different genes. It emphasizes that this test is relevant for linked genes and specifically for recessive traits, whereby complementary mutations may not occur if they are in the same gene. The key takeaway is the distinction between the interactions of linked versus unlinked genes in this context.

Answer(D) They are performed with linked genes but not with unlin.pdf
- 1. Answer: (D) They are performed with linked genes but not with unlinked genes; The complementation test is also called as cis-trans test. It is used to determine whether two mutations associated with a specific phenotype represent two different forms of the same gene (alleles) (AB/ab) or are variations of two different genes (Ab/aB). The complementation will not occur if the mutations are in the same gene It is relevant for recessive traits (traits normally not present in the phenotype due to masking by a dominant allele).
