polyploidy
Polyploidy allows the formation of new species derived from different ancestors. Polyploid is the condition in which an organism has extra sets of chromosomes.
Polyploidy is the condition in which an organism has extra sets of chromosomes. It can be defined as a chromosomal alteration in which the organism posses more than two complete chromosome sets. Classified as an accident in cell division.
Polyploidy is the condition in which a normally diploid cell or organism acquires one or more additional sets of chromosomes. In other words, the polyploid cell or organism has three or more times the haploid chromosome number. Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis.
Chromosomal disorders can be observed in a human karyotype. It can show whether there are extra chromosomes, or missing chromosomes, or malformed chromosomes, or whether chromosomes have extra pieces, or missing pieces.
Different chromosomes can be easily identified in a karyotype.

A karyotype is the number and visual appearance of the chromosomes in the cell nuclei of an organism or species. A karyotype indicates gender, and whether there are any chromosomal abnormalities.
chromosomes having centromere of same size and position

No , it is caused by a single gene mutation .
47 chromosomes , the extra one is the pair no# 18
The extra set of chromosomes is obtained by replicating the original pair. The two chromosomes end up in different cells at the end of mitosis.

Karyotyping
non-disjunction
The condition in which an organism has complete extra sets of chromosomes is called polyploidy. This condition can cause a number of severe birth defects. Most do not live a full lifespan for their species.
