O objetivo deste material didático é ajudar os estudantes a deduzirem, a partir de resultados de simulações de uma série de experimentos com Drosophila, os padrões de herança de algumas características genéticas. A atividade possibilita a di

Nosso corpo é formado por trilhões de células, organizadas em diversos tecidos. Todas elas se originam de uma única célula – o zigoto - resultado da união de um espermatozóide com o óvulo. À medida que o zigoto se divide e o embrião cresc

A photographic map was made of polytene chromosomes of ovarian nurse cells of Anopheles bellator females. The chromosomes of this species have complete or partial homology with those of A. cruzii, mainly in the telomeric and centromeric regions. Vari

SUMMARYA survey of a natural population of Anopheles cruzii from Aldeia dos Indios, Sao Paulo, Brazil, has disclosed the existence of a highly polymorphic genetic system characterized by the presence of 14 independent paracentric inversions and at le

We have isolated cDNAs coding for a ribonucleoprotein of Drosophila melanogaster that is distinguished by its nearly exclusive presence at only one of the several heat shock puffs in polytene chromosomes of third instar larvae. We determined the nucl

An analysis of the ovarian polytene chromosomes of Anopheles cruzii from three localities in Southeast Brazil revealed the existence of two genetic entities within this morphologically uniform taxon. These cryptic species differed in the banding patt

The previously detected ebony ( e ) locus ( Caizzi et al., 1987 ) consists of a complex gene structure that is divided into seven exons. An open reading frame encoding the putative Ebony protein of 98.5 kDa exhibits homology to a family of peptide sy

The nueleolus organizing region in the salivary gland of Seitlra ocellaris becomes gradually less active as the larvae approach pupation. The cytological visible condensation of the nucleolar puff is paralleled by a decrease in the incorporation of [

SUMMARYAnalyses of the nucleolar organizing region (NOR) of the salivary gland polytene chromosomes of Sciara ocellaris show that at the end of the 4th instar, during the time of metamorphosis induction, the NORs undergo a gradual condensation. The c

The influence of an X-linked recessive mutation, sepia, on the sex determination of a bisexual strain of Sciara ocellaris was studied. It induces an alteration in the sex ratio, especially in the progeny of heterozygous females, increasing the propor
