  1. Friday, April 27, 2012 Homework: Word Wall due on block day Inheritance Test on block day - includes: meiosis, karyotypes, heredity and genetics

  2. Quiz-Style Logbook Check Using your logbook. Complete the assignment. When you are finished- keep on desk We will trade and grade

  3. Make an entry- Entry 43: Genetics Practice- 4/27/12 See attached

  4. Answers to Genetics Practice worksheet Homozygous for each trait: Dark eyes= DD Short legs= ll Wide stripes= WW Simple tail= tt

  5. Heterozygous Long legs= Ll Brown fur= Bb Wide stripes= Ww Complex Tail= Tt

  6. Phenotypes DdTt= dark eyes, complex tail Llbb= Long legs, white fur ddbb= white eyes, white fur

  7. Parents: Bb x Bb Genotypic Ratio: 1 RR: 2Rr: 1 rr Phenotypic Ratio: 3 brown fur: 1 white fur White brown

  8. Vocab Answers • The combination of alleles: Genotype • A characteristic of an organism: Trait • Two alleles are the same: Homozygous • Two alleles are different: Heterozygous • Only one of this allele needed to see trait: Dominant • Part of a chromosome that determines a trait: Gene • Two of this allele needed to see trait: Recessive • A form of a gene: Allele • The observed trait of an organism: Phenotype

  9. - What is the TRAIT for the animals? noseshape - What is the genotype of animal 1? NN - What is the recessive form of the trait? Horizontal nose shape - What is the phenotype for animal 3? Horizontal nose

  10. What is the TRAIT for flowers? Leaf position (evenvs uneven) What is the genotype of flower 1? EE What is the recessive form of the trait? Uneven leaves What is the phenotype for flower 3? Uneven leaves
