Maximizing Heterozygosity in Autopolyploids

  • Chapter
Book cover Polyploidy

Part of the book series: Basic Life Sciences ((BLSC,volume 13))

Abstract

Polyploidy appears dependent on heterozygosity! The largest group of polyploids, the allopolyploids (disomic polyploids), have fixed heterozygosity in the two or more divergent genomes they possess (e.g., wheat, oats, cotton, tobacco, etc.). Hexaploid wheat, for example, although self-pollinated and basically homozygous at loci in each of its three genomes, has internal hybridity among loci with similar function in its three genomes. Disomic polyploids thus are able to capitalize on the merits of both the self- and cross-fertilizing systems (1).
