chromosome
Let an agent explain chromosomes in general biological terms and point to genetic services for testing and counselling, without interpreting personal results.
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 chromosomes in general biological terms and point to genetic services for testing and counselling, without interpreting personal results.
A thread-like structure of DNA and proteins that carries genetic information in cells; humans typically have 23 pairs (22 autosome pairs and the sex chromosomes), and chromosome number and structure vary across species.
What it is for: Carrying and transmitting genetic information.
It can be explain chromosome structure and number; describe karyotypes in general terms; find genetic counselling services; compare chromosome numbers across species.
