(c) • Polyploidy occurs in cells and organisms when there are more than two paired (homologous) set of chromosome founds which controls more than one characters simultaneously. 

• Apomixis is the process of asexual reproduction in which the embryo grow from egg cells without being fertilized. 

• Pleiotropy occurs when a single gene influences multiple phenotypic traits. 

• Polytene is a giant chromosomes found in some two-winged flies.
