Natural Selection Vocabulary Review
Across
- 2. Type of cell division which creates gametes and undergoes genetic recombination which leads to genetic variation.
- 5. physical appearance of an organism
- 6. The father of genetics: studied pea plants to determine which traits are dominant and recessive
- 10. genetic make-up of an organism
- 12. Evidence of earlier life forms which may have become extinct.
- 14. Type of adaptation which allows animals to blend in to the environment
- 16. The type of reproduction which DOES NOT allow for genetic variation because they are exact copies except in cases where they have mutated.
- 18. mechanism of change used by species in order to survive
- 19. The Law of ________ states the newer rock layers will form on top of older rock layers.
- 20. The genetic information which contains the blueprints for everything.
Down
- 1. Type of cell division which occurs to create somatic cells and are exact copies.
- 2. errors in DNA which can lead to variation
- 3. Structures with similar functions but no common ancestry
- 4. Type of adaptation where one animal may appear like another in order to survive
- 7. The process which an organism can adapt to an environment over time
- 8. Structures which no longer serve a purpose and include examples such as wisdom teeth and appendix.
- 9. this type of structure is evidence of evolution in species with similar structures but different functions
- 11. The change of a species over time
- 13. The father of evolution who developed the Theory of Natural Selection by means of evolution by studying different species on the Galapagos Island.
- 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.
- 17. The type of reproduction which allows for genetic variation due to offspring being different from the parents and each other.
