Genetic contribution of paleopolyploidy to
WebPaleopolyploidy refers to ancient genome duplications which occurred at least several million years ago (mya). The genome doubling event could either be an autopolyploidy or an allopolyploidy. Due to functional redundancy, genes are rapidly silenced and/or lost from the duplicated genomes. Most paleopolyploids, through evolutionary time, have ...

WebResearchGate Find and share research WebOct 5, 2009 · Initial analyses of paleopolyploidy in Arabidopsis relied on molecular clock estimates of the rate of synonymous substitutions (K s) to date the age of the various events. Based on these calculations, At -α was thought to have occurred 14.5–86 Ma, At -β some 170–235 Ma, and the At -γ event nearly 300 Ma ( Bowers et al. 2003 ).
