Horizontal transfer of parasitic sex ratio distorters between crustacean hosts [PDF]
, 1998 Parasitic sex ratio distorters were artificially transferred within and between crustacean host species in order to study the effects of parasitism on host fitness and sex determination and to investigate parasite–host specificity. Implantation of Nosema

Mandibular ramus as a strong expressor of sex determinations: A digital radiographic study
Journal of Pharmacy and Bioallied Sciences, 2021 Background: This study aimed to assess the effectiveness of mandibular ramus in gender identification in Haryana population. Materials and Methods: One hundred patients were assessed. Panoramic radiological examination was done. Following parameters were

Comparative analysis of a sex chromosome from the blackchin tilapia, Sarotherodon melanotheron [PDF]
, 2016 Background Inversions and other structural polymorphisms often reduce the rate of recombination between sex chromosomes, making it impossible to fine map sex-determination loci using traditional genetic mapping techniques.

Long-Term Follow-Up of Patients with 46,XY Partial Gonadal Dysgenesis Reared as Males
International Journal of Endocrinology, 2014 Background/Aims. Studies on 46,XY partial gonadal dysgenesis (PGD) have focused on molecular, gonadal, genital, and hormone features; little is known about follow-up. Our aim was to analyze long-term outcomes of PGD. Methods.

Current Biology, 2017 Sex determination is as important for the fitness of plants as it is for animals, but its mechanisms appear to vary much more among plants than among animals, and the expression of gender in plants differs in important respects from that in most animals.

Microbial manipulation of host sex determination [PDF]
, 2012 A recent study in the lepidopteran Ostrinia scapulalis shows that endosymbionts can actively manipulate the sex determination mechanism of their host. Wolbachia bacteria alter the sex-specific splicing of the doublesex master switch gene.

Sex Determination and Differentiation in Teleost: Roles of Genetics, Environment, and Brain
Biology, 2021 The fish reproductive system is a complex biological system. Nonetheless, reproductive organ development is conserved, which starts with sex determination and then sex differentiation.

Somatic sex determination [PDF]
WormBook, 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

Sex determination in Bonellia viridis (Echiura : Bonelliidae) : population dynamics and evolution [PDF]
, 2005 In the echiuran worm Bonellia viridis Rolando, the vast majority of sexually undifferentiated larvae metamorphose into dwarf males that live inside the female when exposed to females, but differentiate into females when developing in the absence of ...
