Does copper tolerance give cadmium tolerance in Mimulus guttatus
Copper tolerance in Mimulus guttatus Fischer ex DC, is controlled by a single major gene, plus a number of minor genes (or modifiers) which elevate copper tolerance. Homozygous copper tolerant and nontolerant lin...

Genetics of arsenic tolerance in Agrostis capillaris L.
The genetic control of arsenic tolerance in Agrostis capillaris is examined by two experiments, one involving natural seed families collected from the wild and one based on the six basic generations from a cross ...

Reproductive isolation as a pleiotropic effect of copper tolerance in Mimulus guttatus?
A genetic system producing postmating reproductive isolation between two populations of Mimulus guttatus is described. In one population, Copperopolis, there is a single gene tightly linked to, or pleiotropic to,...

The genetic control of copper tolerance in the yellow monkey flower, Mimulus guttatus
Evidence is presented that copper tolerance in the yellow monkey flower, Mimulus guttatus is determined primarily by a single major gene. Selfed progenies of segregating T × T families produce families which are ...

The number of genes on the second chromosome of Drosophila melanogaster and a comment on the genetic structure of eukaryotes
Recessive lethals on the second chromosome were extracted from genetically isolated populations in Australia and the U.K. The frequency of allelism, used in a manner analogous to capture-recapture of animal po...
