Presentation Transcript

  1. Marshmallow Meiosis: Rebops Tracy M Harper Instructor, Agribusiness& Science Technology

  2. What is a Rebop? • A ‘animal’ made of marshmallows! • Large Marshmallows : body • Small Marshmallows : humps • Thumbtacks : Antenna • Push Pins: Eyes • Pipe Cleaners : Tail • Tooth Picks : Legs

  3. REBOP AA = one antenna Aa= two antenna aa = zero antenna MM = Three Humps Mm = Three Humps mm = 2 Humps EE = Three Eyes Ee = Three Eyes ee= 2 eyes TT = Curly Tail Tt = curly Tail tt = Straight tail QQ = Red Nose Qq = Orange Nose qq = Yellow Nose LL = Blue Legs Ll = Blue Legs Ll = Red Legs DD = Three Body Segments Dd= Three Body Segments dd = Two Body Segments

  4. REBOP SIRE

  5. REBOP DAM

  6. REBOP OFFSPRING Zero Antenna

  7. Genetic Terms • Genotype: genetic makeup • Phenotype: physical appearance • Heterozygous: Genes are different, Dominant & Recessive • Homozygous: both genes are the same

  8. Genetic Terms • Dominant Traits • Three Eyes; EE and Ee • Three Body Segments; DD and Dd • Three Humps; MM and Mm • Curly Tail; TT and Tt • Blue Legs; LL and Ll

  9. Genetic Terms • Recessive Traits • Two Eyes; ee • Two Body Segments; dd • Two Humps; mm • Straight Tail; tt • Red Legs; ll

  10. Genetic Terms • Additive Traits • Antenna • AA = Zero Antenna • Aa = One Antenna • aa = Two Antenna

  11. Additional Activities • Choose a sire and determine the probability of the phenotypes expressed in the offspring. • Example:

  12. Additional Activities • Choose desirable trait • Select a Sire based on the expression of the trait • Example : • Rebops with three humps grow faster • Choose a Sire that will result in the highest percentage of Rebop offspring with three humps.
