Andree's Gene

The gene responsible for preventing breast development in women when they go through puberty. Women with this gene do not even need a training bra since their breasts are very tiny and almost non-existent. Very hard to distinguish their chest with that of a thin man's chest.

That poor Mecham girl over there never developed any breasts; it's that damned Andree's gene that got passed down to her. Maybe she should consider
getting implants.
