Across
- 3. dominance when two traits produce a blended phenotype
- 6. different forms of genes that result in different traits
- 11. squares Mendel used to determine the probability of traits passing to offspring
- 12. the process by which organisms with certain adaptations survive to pass on their traits to a greater number of offspring
- 15. both traits are present in hybrid offspring, but without blending
- 16. one plus two is?
- 18. two times ten
- 20. letter type that represents the recessive trait
- 21. is represented by the genotype of one capital and one lower case letter (ex. Tt)
- 22. the letters that help you visualize an organisms genetic makeup
- 23. ___________ alleles are genes that have more than two possible alleles

- 14. __________ dominance is controlled by one gene that has only two possible alleles
- 17. a type of trait that is hidden by the presence of a dominate trait
- 19. inheritance where two or more genes interact to produce a single trait
