1. Protein Synthesis analogy: 1) Label the library, cookbook, recipe, words in recipe, waiters (2), food order, ingredients, chef, and food.

2. Vocabulary   genetics   trait   procreate   Gregor Mendel   Punnett squares   dominant   recessive   phenotype   genotype   offspring   homozygous   heterozygous   allele   cross   pure breed   hybrid   expressed   inherit   generation

3. Objective 4: inheritance and genes   How do we inherit genes?   Describe the difference between an inherited trait and a non- inherited trait.   Describe the main differences between mitosis and meiosis.   What process might result in a mutation occurring to DNA?   Describe the specific part of the DNA that is altered when a mutation occurs.   Describe how a mutation could affect the genotype and phenotype of an organism? Describe an example.

4. What do we inherit? https://www.youtube.com/watch?v=aeAL6xThfL8 Diploid cells versus haploid cells

6. Genes are the general title of the protein recipe - Hair Color Alleles are specific title of the protein recipe - Brown Hair Gene: flower color Allele: white flower Allele: purple flower A gene is like ice cream and an allele is like a specific flavor of ice cream

7. What do we inherit? Each chromosome may carry the same allele or may carry a different allele Both chromosomes may carry the allele for blue Eyes OR One chromosome carries the allele for Brown Eyes and the other chromosome carries the allele for blue eyes

8.  Phenotype – what the offspring looks like  Genotype - the genetic description of the gene = the letters that represent the genes Trait- a characteristic that can be inherited

9. Dominant & Recessive  Dominant trait – allele is always expressed  At least one of the chromsomes carries the dominant allele  Written as a capital letter  Recessive trait – only expressed when both chromosomes have the same allele  Written as a lower case letter

10. Homozygous & Heterozygous  Homozygous (aka pure breed):  Homozygous (aka pure breed): the letters or alleles are exactly the same on both chromosomes (TT or tt)   The base pairs are the same in both genes  Heterozygous (aka hybrid):   the letters or alleles on each chromosome are different (Tt)   The base pairs are different on each chromosome in the pair
