5. Part I Which Traits Do You Have? Put a X in the box next to the traits that you have.

16. Dominant Genes If you have a dominant gene, you will have a dominant trait.

17. The traits on the right are the result of having Recessive GENES.

18. Recessive Genes If you do not have a dominant gene, you will have a recessive trait.

19. How to Write Your Genes Genes are represented by letters. Dominant genes are represented by a capital letter. Recessive genes are represented by a lower case letter. Always Use the first letter of the name of the dominant trait. Genes = Traits

41. Goal # 2 Genetic Terms

42. Genetic terms Heredity is… The passing of traits from parents to offspring. Genetics is … The branch of science that studies how traits are passed on.

43. Gene refers to.. A sequence of bases on your DNA. Allele refers to.. One of the two forms of a gene. One allele is inherited from each parent.

44. Genotype refers to.. The genes on the DNA. Use letters to describe the genotype of an organism. Phenotype refers to.. The traits that you have. Use a word to describe the phenotype of an organism

45. Dominant gene refers to.. A capital letter The trait that is expressed. Recessive gene refers to.. A lowercase letter. A trait that will only show if there is not a dominant gene.

46. Homozygous refers to… Having two alleles (letters) that are the same. Example : TT or tt Heterozygous refers to.. Having two alleles (letters) that are different. Example: Tt
