Detailed explanation-1: -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.
Detailed explanation-2: -If a cell’s chromosomes are an exact multiple of 23 (46, 69, 92 in humans), those cells are referred to aseuploid. Polyploid cells are euploid cells with more than the normaldiploid number of 46 (2n) chromosomes: 3n, 4n.
Detailed explanation-3: -polyploidy, 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.
Detailed explanation-4: -Most mammals are diploid, like humans, but some organisms are polyploid, meaning they have more than two sets of each chromosome.
Detailed explanation-5: -Polyploids are species in which three or more sets of chromosomes coexist. Polyploidy frequently occurs in plants and plays a major role in their evolution. Based on their origin, polyploid species can be divided into two groups: autopolyploids and allopolyploids.
