Phased Cannabis sex chromosomes, X/Y evolution, and an X-linked ACS/ethylene-pathway mechanism associated with female inflorescence fate; supports chromosome-level context while avoiding one-gene explanations for all sex expression.
Visual lesson 07
Sex chromosomes & early gene regulation
Connect the common XX/XY chromosome system documented in dioecious hemp with sex-linked and sex-biased gene expression that can precede visible floral differentiation, while avoiding the claim that one gene alone determines every expression outcome.
Primary visual specification
XX/XY chromosome context to early sex-biased expression timeline
Create an academically accurate xx/xy chromosome context to early sex-biased expression timeline for the Sex chromosomes & early gene regulation lesson. Use neutral studio lighting or clean academic illustration conventions, realistic botanical proportions, readable labels where needed, no yellow cast, and no decorative elements that compete with the teaching objective.
