Legitimate and honest question which is not an attempt to insult or devalue you: Do you personally consider 4/5 cousins in a generation of a family being queer

Legitimate and honest question which is not an attempt to insult or devalue you: Do you personally consider 4/5 cousins in a generation of a family being queer (to my understanding this means not heterosexual) to be a statistical anomaly, or have you pinpointed a cause or causes for this outlier? Feel free to not answer if it's a painful thing.
