5 True/False Questions

  1. what is the ultimate source of genetic variationa genetic constraint that prevents an organism from making a change that would improve its fitness because it lacks the prerequisite genes.


  2. overtime do species develop more complex traits due to evolutionstruggle for existance among individuals, there are differences in survival and reproduction among individuals, over time differential survival and reproduction changes the population
