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

2. Agenda Review genetics Worksheet Movie

4. Homozygous (pure bred) Same HH hh

5. Heterozygous (hybrid) Different Hh Rr

6. Genotype Allele makeup of an individual Tt T Ttt RRRrrr

7. Phenotype Observable characteristics of an individual

8. Probability Likelihood a specific event will occur Ratio 3:42:4 Percent6022/8023 =.75 = 75% 200/400 =.5 = 50%

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
