Question
Which best captures why the chapter introduces snail sex-change and reptile temperature-dependent sex determination before explaining human XY determination? specific genetic mechanism in humans
To show that no species has any consistent method of sex determination
To illustrate that sex determination mechanisms vary across species before focusing on the
Because reptiles and snails are more important than humans
To prove that humans also change sex like snails
Answer
To illustrate that sex determination mechanisms vary across species before focusing on the
Detailed Explanation
These examples are introduced to show the diversity of sex-determination strategies across species, setting up a contrast with the specific genetic (XY) mechanism used in humans.
