"The first distinction to make is between sex and gender. Sex refers to the biological categories of female and male, categories distinguished by genes, chromosomes, and hormones. Culture has no influence on one’s sex. Sex is a relatively stable category that is not easily changed, although recent technology has allowed people to change their biological sex. Gender, by contrast, is a much more fluid category. It refers to the social categories of male and female. These categories are distinguished from one another by a set of psychological features and role attributes that society has assigned to the biological category of sex."
(Helgeson, Vicki S. The Psychology of Gender. 4th ed. Boston: Pearson, 2012. p. 3)
* No, biologists do not define sex in terms of genes, chromosomes, or hormones, but in terms of
gametes, of
different gamete sizes: Males produce comparatively small and usually mobile gametes called sperm cells, and females produce comparatively large and usually immobile gametes called egg cells.
* No, it is not the case that "recent technology has allowed people to change their biological sex," because it cannot turn
sperm-producers (= males) into
ova-producers (= females), or vice versa. This might become possible in the far future; but it's not possible now, there being many physical/physiological obstacles in the way of progress.
"gender: social, cultural, and psychological traits linked to males and females that define them as masculine or feminine"
(Lindsey, Linda L. Gender Roles: A Sociological Perspective. 6th ed. New York: Routledge, 2016. p. 523)
Okay, but
corporeal/physical features also play a role when it comes to describing or perceiving someone as masculine or feminine. How someone('s body)
looks matters too!
"Distinguishing Sex and Gender
As gender issues become more mainstreamed in scientific research and media reports, confusion associated with the terms sex and gender has decreased. In sociology, these terms are now fairly standardized to refer to different content areas. Sex refers to the biological characteristics distinguishing male and female. This definition emphasizes male and female differences in chromosomes, anatomy, hormones, reproductive systems, and other physiological components. Gender refers to those social, cultural, and psychological traits linked to males and females through particular social contexts. Sex makes us male or female; gender makes us masculine or feminine. Sex is an ascribed status because a person is born with it, but gender is an achieved status because it must be learned.
…
Gender can be viewed on a continuum of characteristics demonstrated by a person regardless of the person’s biological sex. Adding the concept of role to either sex or gender may increase confusion in terminology. When the sociological concept of role is combined with the biological concept of sex, there is often misunderstanding about what content areas are subsumed under the resultant sex role label. Usage has become standardized, however, and most sociologists now employ gender role rather than sex role in their writing. Gender roles, therefore, are the expected attitudes and behaviors a society associates with each sex. This definition places gender squarely in the sociocultural context."
(Lindsey, Linda L. Gender Roles: A Sociological Perspective. 6th ed. New York: Routledge, 2016. pp. 4-5)
* No, sex is not "an ascribed status", but a
natural status that exists ascription-independently.
* Sex also plays a role in making us (appear/look) masculine or feminine, because there are sex-determined
physical characteristics which contribute to a person's masculinity or femininity. For example, having a beard makes a man look more masculine.
