sex-determination system
Let an agent explain sex-determination systems and their diversity across organisms, describe genetic, chromosomal and environmental mechanisms, describe their evolution, and support learning in biology with careful and neutral language.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain sex-determination systems and their diversity across organisms, describe genetic, chromosomal and environmental mechanisms, describe their evolution, and support learning in biology with careful and neutral language.
A biological system that determines the development of sexual characteristics in an organism, including chromosomal systems such as the XY system of mammals and the ZW system of birds, haplodiploidy in many insects, temperature-dependent sex determination in reptiles, environmental and social determination in some fish, and mating type determination in fungi and algae, operating through genes and hormones in primary and secondary sex determination; sex-determination systems vary widely across life and are studied in genetics, developmental and evolutionary biology.
What it is for: Mechanisms determining biological sex.
It can be explain systems and diversity; describe mechanisms; describe evolution; support learning.
Distinguishing features
Diverse mechanisms
Genetic or environmental
Primary and secondary determination
Evolutionary turnover
What it looks like
Not physical; a biological mechanism.
How it is recognised
Mechanism determining sexual development
XY, ZW, haplodiploid, temperature-dependent, mating types
Gender is a social and personal category; sexual differentiation follows determination
