D. } Individuals of this species varied in the amount of webbing in their feet, with some individuals having more webbing and some having less. D. Traits must be inherited from one generation to the next. Why or why not?Yes, all individuals can change a little and pass those changes on to their offspring.Yes, some individuals can change a little and pass those changes on to their offspring.Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring.No, species do not change even after many generations, so individuals of the same species would not look different.Q6.6.
