 Analogous problems also arise for accounts on which the status conferring feature is species membership or being in a special relationship. Possession of the features that qualify one for species membership may be incomplete and a matter of degree (consider Turner Syndrome where one is missing or partially missing the X chromosome) and relationships can be stronger or weaker. The strength of a relationship might depend, for example, on how robustly one instantiates the features defining the relationship (e.g., how robustly one qualifies as a member of a community) or on how well one actively relates (e.g., a child is a more active participant in a relationship than a fetus).
