Errors in the Elimination of X Chromosomes in SCIARA OCELLARIS.
It was previously assumed that the X-linked recessive mutation, sepia, induced errors in X-chromosome elimination during early embryogenesis of Sciara ocellaris. The results obtained in the presentExpand

Dosage compensation in sciarids is achieved by hypertranscription of the single X chromosome in males.
Dosage compensation refers to the process whereby females and males with different doses of sex chromosomes have similar amounts of products from sex chromosome-linked genes. We analyzed the processExpand

Role of microtubules and microtubule organizing centers on meiotic chromosome elimination in Sciara ocellaris.
Spindle formation and chromosome elimination during male meiosis in Sciara ocellaris (Diptera, Sciaridae) has been studied by immunofluorescence techniques. During meiosis I a monopolar spindle isExpand

Evidence for selective differences in single-band polytene chromosome polymorphism in Sciara ocellaris.
Sciara ocellaris (Bradysia tritici) is a dipteran species characterized by an extensive polymorphism of structural modifications of single bands occurring in the polytene chromosomes. In thisExpand

Sex chromatin in somatic cells of the Philander opossum quica (Temminck, 1827, Marsupialia).
In both sexes the Brazilian marsupial Philander opossum quica (Temminck, 1827) presents one conspicuous chromocenter in its somatic cells at interphase. The sex chromatin body in ma
