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