Detailed explanation-1: -Examples of important polyploid plants used for human food include, Triticum aestivum (wheat), Arachis hypogaea (peanut), Avena sativa (oat), Musa sp. (banana), many agricultural Brassica species, Solanum tuberosum (potato), Fragaria ananassa (strawberry), and Coffea arabica (coffee).
Detailed explanation-2: -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-3: -Chromosome number, or ploidy, is an important concept in regards to cell replication and division. Somatic cells, which are most cells in the body, are diploid, meaning that the cell doubles its chromosome number to 4N during mitosis before dividing and the resulting daughter cells are 2N.
