Abstract Polyploid organisms are eukaryotes that have more than two complete sets of chromosomes (one from each parent or ancestor) in somatic and germline cells of animals, fungi, and plants. Polyploidy of individual cells…

Transposable Elements in the Musa and Banana Genome: PAGXXIII conference talk
There has been a lot of talk about transposable elements during the Plant and Animal Genome #PAGXXIII meeting this week. As half or more – often 75% – of all the DNA in a plant or animal genome is typically made of class I retrotransposons and class II DNA transposons, this widespread interest is right!…
