Population cytogenetics.
Chromosome variants are well established as useful genetic markers and integral components both of the genetic structure of populations, and in speciation. The current explosion of molecular techniques is facilitating the localization of many DNA sequences, while a reassessment of the fitness of chromosome mutants challenges some classical views on polymorphism and polytypy. Recent experiments on hybrid zones and mathematical modelling have greatly clarified the formation and evolution of chromosome races.
