1. Cytological characterization of an Aspergillus nidulans mutant from a strain with chromosomic duplication
A development mutant, named V103, was obtained spontaneously from the A strain of A. nidulans. The A strain contains a duplicated segment of chromosome I that has undergone translocation to chromosome II (I → II). It is mitotically unstable and generates phenotypically deteriorated types, some with enhanced stability. The deteriorated variants of A. nidula

2. MicropropagaÃÃo e duplicaÃÃo cromossÃmica de hÃbridos triplÃides de capim-elefante e milheto / MicropropagaÃÃo e DuplicaÃÃo CromossÃmica de HÃbridos TriplÃides de Capim-elefante &Milheto.
Interspecific triploid (3x) hybrids, obtained through the combination of elefant-grass (2n = 4x = 28) with pearl milet (2n = 2x = 14) can overcome their ancestors in production and forage quality. Therefore, they are an alternative to obtain superior cultivars, contributing to increase the production and profit in milk production. However, the greatest limit

3. Dosage Compensation in DROSOPHILA MELANOGASTER Triploids. II. Glucose-6-Phosphate Dehydrogenase Activity
The level of activity of the enzyme glucose-6-phosphate dehydrogenase was determinel in flies having seven different chromosomic constitutions. All those having an integral number of chromosomes [XAA, XXAA, XAAA, XXAAA, and XXXAAA (X=X chromosome, A=set of autosomes)] were found to have similar units of enzyme activity/mg live weight, while diploid females w
