Chromosomal characteristics and karyotype evolution of oxyopidae spiders (araneae, entelegynae)
(2011-05-16)
We made a cytogenetic analysis of four species of Oxyopidae and compared it with the karyotype data of all species of this family. In Hamataliwa sp, the mitotic cells showed 2n♂ = 26+X 1X 2 and telocentric chromosomes. The ...

Cytogenetic description of the Amazonian brown brocket Mazama nemorivaga (Artiodactyla, Cervidae)
(2013-05-27)
The Amazonian brown brocket Mazama nemorivaga (Cuvier, 1817) is a small to medium-sized deer from the Amazon rainforest and ecotones. The first karyotype described was 2n=67 to 69 + 2-7 B and FN= 69-72, in which all ...

Meiotic pairing of B chromosomes, multiple sexual system, and Robertsonian fusion in the red brocket deer Mazama americana (Mammalia, Cervidae)
(2013-09-13)
Deer species of the genus Mazama show significant inter and intraspecific chromosomal variation due to the occurrence of rearrangements and B chromosomes. Given that carriers of aneuploidies and structural rearrangements ...

Sex-Linked Chromosome Heterozygosity in Males of Tityus confluens (Buthidae): A Clue about the Presence of Sex Chromosomes in Scorpions
(Public Library of Science, 2016-10)
Scorpions of the genus Tityus show holokinetic chromosomes, achiasmatic male meiosis and an absence of heteromorphic sex chromosomes, like all Buthidae. In this work, we analysed the meiotic behaviour and chromosome ...
Sex Chromosome Turnover in Moths of the Diverse Superfamily Gelechioidea
(Oxford University Press, 2019-04-08)
Sex chromosomes play a central role in genetics of speciation and their turnover was suggested to promote divergence. Invertebrates, sex chromosome–autosome fusions resulting in neo-sex chromosomes occur frequently in male ...
