Polyploids in which all the chromosome sets are homologous are termed Autopolyploid.
Polyploidy is a condition in which the cells of an organism have more than one pair of (homologous) chromosomes.
Autopolyploidization can occur when the pairs of homologous chromosomes have not separated into different nuclei during meiosis. The resulting gametes will be diploid rather than haploid.
