43 Behavior – assessment 10/28 BrainPOP formative assessment from handout

44 Adaptations 10/28 Behavioral- activities: Migration, hibernation Structural- body parts: webbed feet, fur, color, feathers, wings, etc.

45 Adaptations “Reciprocal reading” 10/28 Read polar bear article Open response

46 bellringer 10/29/09 1. Wings on a bird is what type of adaptation? A. Structural B. behavioral 2. A bear hibernating for the winter is what type of adaptation? A. Structural B. behavioral

47 Adaptations “Reciprocal reading” 10/29 (finished) Read polar bear article Open response A. Describe 3 ways in which the baby cub polar bear will resemble its mother. B. Describe 1 behavior that the baby cub will have to learn from its mother.

48 Bellringer 10/30 Have open response ready to review – finish if needed

49 Make a foldable with 8 strips 10/30 1.Gene- part of a chromosome that has the information about a trait 2.Trait – inherited characteristic ex. Eye color, hair color, etc. 3. Allele- each gene of the gene pair; they combine to determine how the trait is shown Ex. Attached earlobe= a Unattached earlobe=A

50 Genes mom +dad = 1 pair chromosomes

51 Traits: Lab activity 10/30 “Genetic traits: the unique you” Hook: How are 3 genetic traits expressed among your classmates? Workbook P. 7-8 Suggestions: earlobe, curl tongue, curly or straight hair, freckles, dimples

52 Dominant and recessive 11/2/09

53 Bellringer 11/2/09 write question and answer 1. “Freckles” is an example of a type of a. Trait b. Genec. chromosome

54 Previously…..11/2 During the last class, we created foldables with information about genes, alleles, and traits. We introduced different types of traits and collected data by performing a class survey involving 3 different traits.

55 Alleles 11/2 Each individual usually has 2 alleles (or genes) for each trait. For example, you have 2 alleles for dimples, 2 more for freckles, and 2 more for unattached or attached earlobes. Infer…. From previous information, where does the 2 alleles come from that determine a trait? It is how these 2 alleles are combined that determines which trait is shown.

56 Heredity 11/2 Hook: What does flipping a coin have in common with heredity?

57 Alleles 11/2 Each of your parents have 2 alleles for a trait Usually you receive one allele from the female parent and one from the male parent Chance, or luck, determines which gene you get from each parent….just like flipping a coin

58 Heredity video clip 11/2 http://www.brainpop.com/health/geneticsgro wthanddevelopment/heredity/ http://www.brainpop.com/health/geneticsgro wthanddevelopment/heredity/

59 Alleles- 11/2 complete foldable with these notes Dominant allele- covers or hides the other allele “bully” – Capital letter Recessive allele – is covered or hid because of the other allele – Lower case letter

60 Example of allele combinations 11/2 1. The trait is freckles freckles = A no freckles = a Infer…. What trait will result? AA = aa = Aa =

61 Alleles- 11/2 complete foldable with these notes Dominant allele- blocks or hides the other allele – Capital letter – Shows when dominant + dominant OR dominant + recessive combine; AA or Aa Recessive allele – is blocked or hid because of the other allele – Lower case letter – Only shows when recessive + recessive combine; aa

62 Pure vs. hybrid 11/2 Pure = genes are the same for a trait AA or aa Hybrid = genes are different for a trait Aa

63 Allele lab activity 11/2 Each table should have 2 bags, one labeled with “Mom” and the other with “Dad” There should be two alleles in each bag, one “A” and the other “a” These two parents will have 10 offspring Lab worksheet “Identifying alleles” Review instructions Model with bags and how to fill out worksheet

64 Formative assessment “DR” 11-2-09 Use this information to help answer the following questions: A = Freckles a = no freckles 1.According to the above information, what type of allele is freckles? a. Dominantb. Recessivec. Neitherd. Both 2.What type of allele is “no freckles”? a. Dominantb. Recessivec. Neitherd. Both 3. If an offspring has an allele combination of Aa, what trait will be shown by that offspring? a. Frecklesb. No frecklesc. Will not knowd. Both 4.What allele combination must an offspring have to show “no freckles”? a. AAb. Aac. aad. None of these

65 Bellringer 11-3-09 If W = widow’s peak and w = no widow’s peak, what allele combination might show a widow’s peak? A. WW B. Ww C. ww D. Both Ww and WW E. All of the above

66 Mutations, variation, specialized breeding 11/3 Mutation – permanent change in DNA May be beneficial, harmful, or neutral for the organism Ex. 4 leaf clover Caused by viruses, radiation, etc. Variations- different ways a trait can show itself- Ex. Eye color, skin color, hair color Specialized breeding – to create animals with desired traits
