The origin of the word gender came from the Old French "gendre" (now termed "genre"), which meant "kind, sort, genus." Generally, children are assigned to their gender at birth based on their anatomy and chromosomes. For most children, this gender assignment corresponds to their gender identity, an innate sense of identifying oneself as male or female. Some children might experience incongruity and grow into transgender adults.| www.ncbi.nlm.nih.gov
