A CRISPR-Cas9 sex-ratio distortion system for genetic control. [PDF]

open access: yes, 2016
Genetic control aims to reduce the ability of insect pest populations to cause harm via the release of modified insects. One strategy is to bias the reproductive sex ratio towards males so that a population decreases in size or is eliminated altogether ...

Somatic sex determination [PDF]

open access: yesWormBook, 2006
C. elegans occurs in two natural sexes, the XX hermaphrodite and the XO male, which differ extensively in anatomy, physiology, and behavior. All somatic differences between the sexes result from the differential activity of a "global" sex determination regulatory pathway. This pathway also controls X chromosome dosage compensation, which is coordinated

Evolutionary diversity and turn-over of sex determination in teleost fishes. [PDF]

open access: yes, 2009
Sex determination, due to the obvious association with reproduction and Darwinian fitness, has been traditionally assumed to be a relatively conserved trait.

Pengaruh suhu lingkungan tropis terhadap penentuan jenis kelamin drosophila

open access: yesJournal of Biological Researches, 2012
Based on many research studies conducted it can be concluded that there are more than 250 theories of sex-determination. This means that there is not any single theory on sex-determination. This study aims at uncovering effects of the temperature of the

Identification of general patterns of sex-biased expression in Daphnia, a genus with environmental sex determination [PDF]

open access: yes, 2018
Daphnia reproduce by cyclic-parthenogenesis, where phases of asexual reproduction are intermitted by sexual production of diapause stages. This life cycle, together with environmental sex determination, allow the comparison of gene expression between ...

The mir-35 Family Links Maternal Germline Sex to Embryonic Viability in Caenorhabditis elegans

open access: yesG3: Genes, Genomes, Genetics, 2019
The germline sex determination pathway in C. elegans determines whether germ cells develop as oocytes or sperm, with no previously known effect on viability. The mir-35 family of microRNAs are expressed in the C.

Fog-2 and the evolution of self-fertile hermaphroditism in caenorhabditis [PDF]

open access: yes, 2004
Somatic and germline sex determination pathways have diverged significantly in animals, making comparisons between taxa difficult. To overcome this difficulty, we compared the genes in the germline sex determination pathways of Caenorhabditis elegans and

Recurrent Modification of a Conserved Cis-Regulatory Element Underlies Fruit Fly Pigmentation Diversity [PDF]

open access: yes, 2013
The development of morphological traits occurs through the collective action of networks of genes connected at the level of gene expression. As any node in a network may be a target of evolutionary change, the recurrent targeting of the same node would ...

Cheiloscopy: A Deterministic Aid for Forensic Sex Determination

open access: yesJournal of Indian Academy of Oral Medicine and Radiology, 2011
Background: Cheiloscopy, the study of lip prints, is an upcoming tool for the identification of persons. The lip print of every person is unique and can be used to fix personal identity.

Progress in studies of sex determination mechanisms and sex control techniques in Cynoglossus semilaevis (half-smooth tongue sole) [PDF]

open access: yesFrontiers of Agricultural Science and Engineering, 2016
The Cynoglossus semilaevis (half-smooth tongue sole) is a marine flatfish of great commercial value for fisheries and aquaculture in China. It has a female heterogametic sex determination system (ZW/ZZ) and environmental factors can induce sex-reversal ...
