Answer: One kind of floral organ is replaced by another.
For a simple example of a complementation test suppose a geneticist is interested in studying two strains of white-eyed flies of the species Drosophila melanogaster more commonly known as the common fruit fly.In this species wild type flies have red eyes and eye color is known to be related to two genes A and B . Each one of these genes has two alleles a dominant one that codes for a …

Pleiotropy – Wikipedia
Pleiotropy (from Greek πλείων pleion “more” and τρόπος tropos “way”) occurs when one gene influences two or more seemingly unrelated phenotypic traits.Such a gene that exhibits multiple phenotypic expression is called a pleiotropic gene. Mutation in a pleiotropic gene may have an effect on several traits simultaneously due to the gene coding for a product used by a myriad of …
Transgenerational epigenetic inheritance is the transmission of epigenetic markers from one organism to the next (i.e. from parent to child) that affects the traits of offspring without altering the primary structure of DNA (i.e. the sequence of nucleotides): 168 —in other words epigenetically.The less precise term “epigenetic inheritance” may cover both cell–cell and organism–organism …
X-inactivation (also called Lyonization after English geneticist Mary Lyon) is a process by which one of the copies of the X chromosome is inactivated in therian female mammals.The inactive X chromosome is silenced by it being packaged into a transcriptionally inactive structure called heterochromatin.As nearly all female mammals have two X chromosomes X-inactivation prevents them from …
