The functional units of macronuclear assortment in Tetrahymena thermophila
Published online by Cambridge University Press: 14 April 2009
Summary
Macronuclei assorting simultaneously for H, Chx, Mpr, and co, and containing only one or two copies of the HD allele produced several combinations of phenotypes at the other loci, instead of only one or two such combinations. It follows that macronuclear subnuclei, if they exist at all, must frequently exchange parts. Models involving somatic recombination, transient subnuclei, or progressive chromosome fragmentation are discussed as possible explanations.
