Presentation Transcript

  1. Welcome! Please find your seat using the seating chart

  2. Agenda • Review genetics • Worksheet • Movie

  3. REVIEW

  4. Homozygous (pure bred) Same HH hh

  5. Heterozygous (hybrid) Different Hh Rr

  6. Genotype Allele makeup of an individual Tt T T tt RR Rr rr

  7. Phenotype Observable characteristics of an individual

  8. Probability Likelihood a specific event will occur Percent 6022/8023 = .75 = 75% 200/400 = .5 = 50% Ratio 3:4 2:4

  9. Punnett Squares Let’s Practice

  10. Incomplete Dominance • one allele for a trait is not completely dominant over the other allele • Combined phenotype (blended) R = allele for red flowers W = allele for white flowers red x white ---> pink RR x WW ---> 100% RW

  11. Co-dominance • In COdominance, the "recessive" & "dominant" traits appear together in the phenotype of hybrid organisms

  12. Practice With Genetics
