However, 40% of the students in the genetics of human sex condition and 16% in the genetics of plant sex condition used gender language in their responses. The patterns associated with students who use gender language in their responses in the genetics of plant or human sex conditions are indicative of conflation. ...Conflation of biological sex and gender has been shown to engender unscientific essentialist beliefs about the nature of human difference that could manifest in sexism and transphobia.

The next most common response category pertained to responses in which participants simply provided the terms male and female, without any further description or explanation. Examples of such responses included: 'Gender would be male/female' (A2P45) and 'Male or female' (C3P48). ... As shown, similar proportions of Australian and Canadian participants provided responses that were coded as Feelings/Identification or that were coded as Biology. The stark difference in response patterns by country pertained to responses that were coded as Male/Female: This was the modal category for the Australian participants, with nearly one‐third of participants providing such a response, whereas Male/Female was not even in the top three response categories for the Canadian participants.
