WebThe position effects are of two types: (i) Stable type or S-type (cis-trans type), and. (ii) Variegated type or V-type. An example of the stable type of position effect is the “Bar-eye” phenotype of Drosophila. The Bar eye phenotype is the result of a duplication of the 16A region of the X chromosome (Fig. 13.6). Web17q12 duplication occurs when a portion of chromosome 17 is duplicated. When the duplication is inherited from a parent, it is inherited in an autosomal dominant manner. The duplication may be suspected if a doctor sees signs and symptoms such as developmental delay, behavioral problems, and intellectual disability.
