sex determination

Evidence from various sciences reveals that there are diverse ways of being male, female, or both. An anthropologist argues that embracing these truths will help humans flourish.

Removing microRNA that caused conversion of male mice embryos into female sheds light on key noncoding elements in sex determination.

Working with bacteriophages and nematodes, the University of California, Berkeley, molecular biologist uncovered a role for genetic switches in early development.

The near-complete feminization of northern Great Barrier Reef sea turtles has been blamed on climate change.

A proposed mechanism for how bearded dragons with male chromosomes hatch as females at high temperatures

Researchers solve the mystery of 15-year-old mutant ferns with disrupted sex determination.

The amino acids left behind in a human fingerprint can be used to determine whether an individual is male or female.

Sex differences in processing pain; clue in flu vaccine–narcolepsy link found; early antibiotic use affects the gut microbiome; lizard sex determined by genes, then temperature

Researchers find that microRNAs may play a role some of the sexual differences seen in fruit flies.

The finding is the first case of sex determination that does not involve a protein and may one day be a boon to silk manufacturers.

What researchers are learning as they sequence, map, and decode species’ genomes

Two genes from the Y chromosome are sufficient to generate male mice capable of fathering healthy offspring via an assisted reproductive technique.
