Female sex inversion as a reason for an unbalanced sex ratio in the neotropical species Brycon orbignyanus
(2022-04-01)
The objective of this study was to temporally identify sex differentiation to morphologically characterize the formation of female and male germinal epithelium and verify the occurrence of the sex disproportion reported ...
Neo-sex chromosomes of Ronderosia bergi: insight into the evolution of sex chromosomes in grasshoppers
(Springer-Verlag Berlin Heidelberg, 2015)
Sex chromosomes have evolved many times from morphologically identical autosome pairs, most often presenting several recombination suppression events, followed by accumulation of repetitive DNA sequences. In Orthoptera, ...
Neo-sex chromosomes of Ronderosia bergi: insight into the evolution of sex chromosomes in grasshoppers
(Springer, 2015-09)
Sex chromosomes have evolved many times from morphologically identical autosome pairs, most often presenting several recombination suppression events, followed by accumulation of repetitive DNA sequences. In Orthoptera, ...

High dynamism for neo-sex chromosomes: satellite DNAs reveal complex evolution in a grasshopper
(2020-09-01)
A common characteristic of sex chromosomes is the accumulation of repetitive DNA, which accounts for their diversification and degeneration. In grasshoppers, the X0 sex-determining system in males is considered ancestral. ...
Homomorphic Sex Chromosomes and the Intriguing Y Chromosome of Ctenomys Rodent Species (Rodentia, Ctenomyidae)
(Karger, 2014-01-01)
Unlike the X chromosome, the mammalian Y chromosome undergoes evolutionary decay resulting in small size. This sex chromosomal heteromorphism, observed in most species of the fossorial rodent Ctenomys, contrasts with the ...
