Ascientist hypothesizes that temperature affects the gender of a species of turtle. how can the scientist test this hypothesis?

In some of the species, like lizards, crocodiles, and turtles, the determination of gender is influenced by temperature. In case of turtles, the eggs turn into male when the temperature is less, and turn into females when the temperature is higher. Therefore, in order to hypothesize that the determination of gender in turtles is influenced by temperature, the scientist should expose the distinct groups of turtles into distinct sets of temperatures in a lab.

thinking it would be physical characteristics

yes it is weird but true
