Not in humans, no! While in some animals sex determination is purely about X dosage (Drosophila), in humans the Y chromosome is actually sex-determining. In females the second X chromosome actually gets inactivated as a means of gene dosage compensation.

Be civil, remember the human.
No insulting or harassing other members. That includes name calling.
Censor any identifying info of private individuals in the posts. This includes surnames and social media handles.
Respect differences of opinion. Civil discussion/debate is fine, arguing is not. Criticise ideas, not people.
Keep unrequested/unstructured critique to a minimum. If you wish to discuss how this community is run please comment on the stickied post so all meta conversations are in one place.
Remember we have all chosen to be here voluntarily. Respect the spent time and effort people have spent creating posts in order to share something they find amusing with you.
Swearing in general is fine, swearing to insult another commenter isn’t.
No racism, sexism, homophobia, transphobia, xenophobia or any other type of bigotry.
No incitement of violence or promotion of violent ideologies.

Please report comments that break site or community rules to the mods. If you break the rules you’ll receive one warning before being banned from this community.
