Duplication of 17th chromosome
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).
