What does sex determination mean?
Answer and explanation
Correct answer: Determining whether offspring will be male or female
Sex determination is the biological process by which the sex of offspring is established. In humans, it is associated with the sex-chromosome combination formed at fertilisation: XX is typically female and XY is typically male. Therefore option A gives the correct meaning. Food choice, breathing rate and eye-colour change are unrelated biological processes, not definitions of sex determination.
