3. EXPLAIN THE DIFFERENCE BETWEEN A PHENOTYPE & GENOTYPE Answer: A phenotype shows on the outside-all traits. A genotype MAY show on the outside- the genetic make-up

4. WHO AM I? I AM AN ALTERNATIVE FORM OF A GENE Answer: ALLELE

5. WHICH TYPE OF DOMINANCE? -COMPLETE DOMINANCE -INCOMPLETE DOMINANCE -CODOMINANCE View next 5 slides.

6. Complete Dominance

7. INCOMPLETE DOMINANCE

8. CODOMINANCE

10. NOTHING- A JOKE

11. Complete Dominance is when… A) both traits are blended together B) only one trait shows (dominant one) C) both traits are seen equally so both show at the same time.

12. A) BOTH TRAITS ARE BLENDED TOGETHER B) ONLY ONE TRAIT SHOWS (DOMINANT ONE) C) BOTH TRAITS ARE SEEN EQUALLY SO BOTH SHOW AT THE SAME TIME. INCOMPLETE DOMINANCE is when…

13. A) BOTH TRAITS ARE BLENDED TOGETHER B) ONLY ONE TRAIT SHOWS (DOMINANT ONE) C) BOTH TRAITS ARE SEEN EQUALLY SO BOTH SHOW AT THE SAME TIME. CODOMINANCE is when…

14. Mary is tall like her mother. Her sister, Jamie, is short like her father. If tall is dominant over short, what is the genotype for each sister? If you can’t determine this explain why. Jamie is tt or pure bred short (since short shows) Mary is hybrid tall Tt- You know this since her mother must be Hybrid-Jamie has tt.

15. EXAMPLE: DD HOMOZYGOUS OR PURE BRED If the alleles match, what can it be called. Name two ways it can be stated.

16. If the alleles DO NOT match, what can it be called. Name two ways it can be stated. EXAMPLE: Dd HETEROZYGOUS OR HYBRID
