SUBJECT INDEX

For the period 1951-1960

Monogenic traits are listed under "mutant"; traits of uncertain inheritance are listed under "character." No attempt has been made to index all linkage segregations. Significant indications of linkage are listed under their respective chromosomes. Linkage tests for new mutants are indexed according to the symbol of the new mutant.
