CHROMOSOMAL POLYMORPHISM IN DROSOPHILA EURONOTUSl

TUDY of the naturally occurring polymorphism found in the banded polytene Schromosomes of Diptera has yielded a great deal of information on the genetic structure of natu -a1 populations, and also in some instances has indicated the pattern of evolut .onary change which has occurred during species formation. Outstanding examples of studies of the latter sort are those in the Drosophila obscura ...

Chromosomal Polymorphism in Drosophila Rubida

HE population geneticist is essentially interested in the variation of gene freTquencies in natural populations. Within chromosomal inversions blocks of genes are contained and in many species of Drosophila due to the presence of easily analysable giant chromosomes, the behavior of these blocks of genes can be easily studied in natural populations. Thus, of recent years chromosomal inversion po...

Chromosomal Polymorphism in the Sporothrix schenckii Complex

Sporotrichosis is a polymorphic disease caused by a complex of thermodimorphic fungi including S. brasiliensis, S. schenckii sensu stricto (s. str.), S. globosa and S. luriei. Humans and animals can acquire the disease through traumatic inoculation of propagules into the subcutaneous tissue. Despite the importance of sporotrichosis as a disease that can take epidemic proportions there are just ...

Mus Terricolor (rodentia, Muridae) Complex: Chromosomal Polymorphism

Mus terricolor chromosomal types I, II, III from different places of India were cytogenetically analyzed. Chromosome types II and III showed polymorphic pericentric inversions of autosomes 2 and 5 present in homozygous or heterozygous condition in the populations. Moreover, besides fixed heterochromatic arms on autosomes 1, 3, and 6; the autosome 8 in terricolor type III showed a large heteroch...

Repetitive DNAs and shrink genomes: A chromosomal analysis in nine Columbidae species (Aves, Columbiformes).

An extensive karyotype variation is found among species belonging to the Columbidae family of birds (Columbiformes), both in diploid number and chromosomal morphology. Although clusters of repetitive DNA sequences play an important role in chromosomal instability, and therefore in chromosomal rearrangements, little is known about their distribution and amount in avian genomes. The aim of this s...
