Based on the following sentence, what can be inferred about mating signals in immature hamsters, rats, and mice?

In one set of experiments with immature hamsters, rats, and mice, researchers found that removing the VNOs—but leaving the olfactory nerves intact—made the rodents much less likely to mate.

Scientists currently believe that humans have approximately 30,000 genes, far fewer than scientists initially estimated.

Each gene has a specific code of base cells responsible for telling the body how it will look, how it will digest food or battle infection, and sometimes even ho
