Do the requirements to honor a Kohen require one to honor a female Kohen?
Background: There is a requirement to honor Kohanim (Vayikra 21:8; Mishneh Torah, Positive Mitzvot, 32; Moed Katan 28b.27). Among the ways this commandment is fulfilled are allowing a Kohen to make Hamotzi and to lead bentching for those present; in a gathering of people, a Kohen should be the first to speak; a non-Kohen should offer a Kohen the best piece of food among that which he is serving to his guests (Mishnah Berurah 201:13); a non-Kohen may not make use of a Kohen (Rema, Orach Chaim 128:45). (There are some exceptions discussed elsewhere, but those are not relevant to the question at hand.)
Question: The same way that certain female relatives of Kohanim (i.e. their wives, and their daughters who are unmarried and never had children) are able to eat Terumah, no different than their male relatives (Vayikra 22:11-13), does the requirement to honor Kohanim extend to these female relatives as well? For example, if a group of women are forming a Zimun (as per Shulchan Aruch, Orach Chaim 199:7) and one of them is married to a Kohen, should they have the Kohen's wife lead?
