- 7. The genetic material in an organism.
- 9. trait Observed only when two recessive factors are present in offspring.
- 10. The process of copying a DNA molecule to make another DNA molecule.
- 12. square A model used to predict possible genotypes and phenotypes of offspring.
- 13. How a trait is expressed.
- 14. What a genotype is when the two alleles of a gene are the same.
- 16. When a proteins being made from RNA.
- 18. The study of how parents pass their traits to their offspring.

- 1. A change in the nucleotide sequence.
- 3. The first step in making a protein.
- 4. The code for making proteins from the nucleus to the cytoplasm is carried in this type of nucleic acid.
- 5. When parents pass their traits to their offspring.
- 6. dominance Neither parents phenotype is visible in the offspring’s phenotype.
- 8. A genes different form.
- 11. In this both parents phenotypes are visible seperately in the offspring's phenotype.
- 13. inheritance This occurs when multiple genes determine the phenotype of a trait.
- 15. The two alleles that control the phenotype of a trait.
- 17. The section on a chromosome that has genetic information.
- 20. trait If only one factor is seen because another factor is blocking it is called this.
