Polyploids—organisms that have multiple sets of chromosomes—are common in certain
plant and animal taxa, and can be surprisingly stable. The evidence that has emerged from …

Publisher Summary This chapter provides a discussion of recent advancements, in context
to plant polyploidy. Polyploidy plays a very important role in plant evolution. Major recent …

Male germ line development in flowering plants is initiated with the formation of the
generative cell that is the progenitor of the two sperm cells. While structural features of the …

The minority cytotype exclusion principle describes how random mating between diploid
and autotetraploid cytotypes hinders establishment of the rare cytotype. We present …

In multivalent polyploids, simultaneous pairings among homologous chromosomes at
meiosis result in a unique cytological phenomenon—double reduction. Double reduction …

THE recent article by Wu and Ma (2005) criticized our article (Luo et al. 2004) on a statistical
method for linkage analysis in autotetraploid species by (i) stating that Luo et al.'s linkage …
