Pay close attention, there may be a test later. I know I am. S o, depending on how you want to count, we've got anywhere from four to nine, maybe ten, natural genders or sexes. It really depends on what criteria you are using to differentiate them. You mentioned all-female species and indeed there are such.
Parthenogenetic species are entirely female.
Most of these species do not mate, but in some, such as the New Mexico whiptailed lizard , there is courtship and mating - although no genetic material is exchanged. Copyright 2000 by The Barbarian Illuminati. All rights reserved.
