  1. 2. Type of cell division which creates gametes and undergoes genetic recombination which leads to genetic variation.
  2. 5. physical appearance of an organism
  3. 6. The father of genetics: studied pea plants to determine which traits are dominant and recessive
  4. 10. genetic make-up of an organism
  5. 12. Evidence of earlier life forms which may have become extinct.
  6. 14. Type of adaptation which allows animals to blend in to the environment
  7. 16. The type of reproduction which DOES NOT allow for genetic variation because they are exact copies except in cases where they have mutated.
  8. 18. mechanism of change used by species in order to survive
  9. 19. The Law of ________ states the newer rock layers will form on top of older rock layers.
  10. 20. The genetic information which contains the blueprints for everything.

  1. 1. Type of cell division which occurs to create somatic cells and are exact copies.
  2. 2. errors in DNA which can lead to variation
  3. 3. Structures with similar functions but no common ancestry
  4. 4. Type of adaptation where one animal may appear like another in order to survive
  5. 7. The process which an organism can adapt to an environment over time
  6. 8. Structures which no longer serve a purpose and include examples such as wisdom teeth and appendix.
  7. 9. this type of structure is evidence of evolution in species with similar structures but different functions
  8. 11. The change of a species over time
  9. 13. The father of evolution who developed the Theory of Natural Selection by means of evolution by studying different species on the Galapagos Island.
  10. 15. Due to genetic ________, beings who reproduce sexually are able to adapt to the environment allowing for traits which are best suited to passed on to the next generation.
  11. 17. The type of reproduction which allows for genetic variation due to offspring being different from the parents and each other.
