Apr. 15, 2021 —Bearded dragon embryos can use two different sets of genes to become a female lizard -- one activated by the sex chromosomes and the other activated by high temperatures during development, ...
Sep. 2, 2021 —The cichlids of Lake Tanganyika in Africa are highly diverse -- including with regard to sex chromosomes. These have changed extremely frequently in the course of the evolution of these fish and, ...
Sep. 9, 2022 —Scientists have known that sex-determination in vertebrates happens in the germ cells, a body's reproductive cells, and the somatic cells, the cells that are not reproductive cells. Yet they ...
Nov. 20, 2020 —A new pair of articles has shown that sexual lineage matters for how offspring receive adaptations from parents in stickleback fish. Researchers studied how parents who were exposed to predators ...
Apr. 13, 2021 —The O. swinhoana frog species is the first vertebrate known to retain descendant genes that now determine sex in mammals, birds, and fishes inherited from a common ...
Nov. 17, 2020 —Scientists have shown that sex-specific differences in variability depend on individual physical and physiological features in mice, debunking competing theories that either males or females are more ...
July 14, 2021 —For 30 years, University of Tokyo Associate Professor Hisayoshi Nozaki has visited the Sagami River to collect algal samples to understand how living things evolved different sexes. The threes sexes ...
Nov. 28, 2022 —The Sox9 gene is upregulated in the absence of sex-determining Y chromosome and Sry gene in Amami spiny ...
Sep. 7, 2020 —Researchers have found that activation of a fatty acid receptor that detects fatty acids in cells and regulates physiological functions causes Japanese rice fish (medaka) to become male. The ...
July 26, 2021 —A new study sheds light on how organisms have evolved to address imbalances in sex chromosomes. The study looks at a species of softshell turtle, but the results could help to illuminate an important ...
