Question

"Some animals rely on environmental cues for sex determination." Justify this statement giving an example.

Hint:

Some species, like certain reptiles, use environmental factors such as temperature to determine the sex of their offspring.

Answer 1

Some animals rely on environmental factors for sex determination. For example, in many species of reptiles such as certain turtles, the sex of the offspring is determined by the temperature at which the eggs are incubated.
- At higher temperatures, more females are produced.
- At lower temperatures, more males are produced. Thus, in these species, the environmental temperature is the primary cue for sex determination.
