Non-invasive foetal sexing : medical test or a new tool for sex selection? [PDF]

, 2011
Recent scientific developments in prenatal testing, based on foetal DNA in maternal blood, now allow non-invasive foetal sexing early in pregnancies at risk of a sex-linked disorder. In such cases, these novel non-invasive tests can improve prenatal care

The quantitative genetic basis of sex ratio variation in Nasonia vitripennis : a QTL study [PDF]

, 2010
Our understanding of how natural selection should shape sex allocation is perhaps more developed than for any other trait. However, this understanding is not matched by our knowledge of the genetic basis of sex allocation.

Population genomic analysis reveals a polygenic sex determination system in Apostichopus japonicus

iScience
Summary: The sea cucumber Apostichopus japonicus, a key species in Chinese aquaculture, plays a significant evolutionary role within the Echinodermata phylum. However, the sex determination mechanism in this species remains poorly understood.

Cytogenetic evidence and dmrt linkage indicate male heterogamety in a non-bilaterian animal.

PLoS ONE, 2023
The diversity of sex determination systems in animals suggests that sex chromosomes evolve independently across different lineages. However, the present data on these systems is largely limited and represented mainly by bilaterian animals.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Pleistocene divergence in the absence of gene flow among populations of a viviparous reptile with intraspecific variation in sex determination

Ecology and Evolution, 2021
Polymorphisms can lead to genetic isolation if there is differential mating success among conspecifics divergent for a trait. Polymorphism for sex‐determining system may fall into this category, given strong selection for the production of viable males ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Genetics of sex determination in tilapiine species

, 2008
We identified DNA markers linked to sex determining genes in six closely related species of tilapiine fishes. The mode of sex determination differed among species.

An Essentialist View of Biological Sex Remains Alive and Well

TheoLogica
In response to a recent article by Myron Penner, April Cordero, and Amanda Nichols in this journal, this essay offers a critical analysis. Their article makes a case against gender essentialism rooted in biology, drawing from the biology of sex ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.
