## Emergence
**Emerges from:** [sex](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-sex.biological), [difference](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-difference.relation), [female](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-female.sex), [people](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-people.social)

**Through:** biological sex and difference interact to distinguish a subclass within persons defined in contrast to female

**Novel properties:**
- sexual distinction in people
- asymmetric contrast to female
- socially situated sex class

## Examples
- In 2023, a human male named Alex Rivera donated blood at a clinic in Toronto, where his XY chromosomes were confirmed via karyotype analysis. *(biology)*
- The 1987 World Health Organization report classified male sex as defined by presence of Y chromosomes and testes in human fetuses observed in prenatal screenings. *(institutions)*
- A 2022 genomic study at MIT compared gene expression in tissue samples from 150 male humans, identifying SRY gene activity on chromosome Y. *(computing)*
