Across
  1. 3. the condition of being color blind
  2. 4. what Mendel used to study heredity
  3. 6. tool that geneticists use to predict the likelihood that an offspring will express specific traits passed down from its parents
  4. 7. the passing on of physical or mental characteristics genetically from one generation to another.
  5. 11. the letters that help you visualize an organism's genetic makeup
  6. 13. when the phenotypes of both parents are present
  7. 16. the dominant trait is always expressed in a hybrid plant
  8. 17. The Father of Genetics
  9. 18. an inherited trait that helps an animal survive to reproduce
  10. 20. when purebreds and hybrid plants are combined
  11. 21. occurs when two or more genes in different places on a chromosome interact to control a single trait
  12. 22. when the ratio of alleles in a population changes randomly over time
Down
  1. 1. an extreme example of genetic drift that happens when the size of a population is severely reduced
  2. 2. traits that appear in a plant / can be seen
  3. 3. the same gene that causes several different results. Eye color is an example
  4. 5. cell that has a nucleus
  5. 8. an offspring with a mix of alleles for a specific trait or character
  6. 9. the trait that an organism expresses as determined by its genotype
  7. 10. the scientific study of genes and heredity
  8. 12. plant that always produces descendants with the same trait
  9. 14. process through which organisms with certain adaptations survive to pass on their traits in a greater number of offspring than other organisms do
  10. 15. humans have 23 pairs of these
  11. 19. traits that are hidden in a plant because the dominant trait takes over
