Detailed explanation-1: -Polyploidy typically results in instant speciation-the new polyploid may be immediately isolated reproductively from its parent or parents; this process greatly increases biodiversity and provides new genetic material for evolution.
Detailed explanation-2: -Polyploidization can lead to higher levels of heterozygosity, which can be confounded in asexually propagated plants such as potato causing greater difficulties in the identification of haplotypes. This is due to multiple alleles from the same locus being mistaken as sequences from different loci (Huang et al., 2017).
Detailed explanation-3: -Polyploidy is the heritable condition of possessing more than two complete sets of chromosomes. Polyploids are common among plants, as well as among certain groups of fish and amphibians. For instance, some salamanders, frogs, and leeches are polyploids.
