Double Reduction in Allotetraploid Peanut and the Role of Chromosomal Imbalance in Unexpected Linkage Map Artifacts

Abstract Polyploidization in peanut (Arachis hypogaea L.) fixed heterosis but also caused a genetic bottleneck isolating cultivated peanut from its wild diploid relatives. Mechanisms such as homoeologous exchange can partially restore genetic diversity by generating new allelic c...
