ically controlled and associated with special sex chromo-

femaleness with one or the other of these being present 
in  most  higher  animals  though  both  may  occur  in  the
same individual in many plants and some invertebrates
and  though  no  such  distinction  can  be  made  in  many 
lower forms (as some fungi, protozoans, and possibly bac-
teria and viruses) either because males and females are 
replaced by mating types or because the participants in
sexual  reproduction  are 
indistinguishable—compare
