Answer:
Gender - Sex.
Step-by-step explanation:
The distinction between gender and sex differentiates a person's biological sex (the anatomy of the individual) from the gender, which is related to how one sees him/herself, with the personal identification of one's own gender.
As the exercise details, gender is used when referring to male-female-other differences that are learned and sex to designate biological, anatomical differences of one's sexual reproduction system.
