1. Okay – Not really

2. Other Patterns of Heredity  Polygenic traits = several genes influence the trait.  Examples: Eye color, weight, height, hair color, & skin color.

3.   Incomplete dominance = a trait that is in between the two parent traits.  Ex: Red snapdragon flower crossed with white snapdragon flower results in PINK snapdragon flowers. Incomplete dominance

5.   Co-dominance = Two dominant alleles are expressed at the same time.  EX: Homozygous red horse crossed with a homozygous white horse results in Red AND white horse Co-dominance

7.   Genes with 3 or more alleles are said to have multiple alleles.  EX: Blood type in humans (ABO) Multiple Alleles

8.  Blood types

9.   Sickle cell anemia  Recessive genetic disorder.  Red blood cells are sickle shaped.  Don’t move well through vessels. Some traits are caused by mutations

10. Possible Genotypes RR = normal red blood cell Rr = slightly curved red blood cell rr = sickle-shaped red blood cell In tropical areas of the world, being heterozygous for sickle cell anemia is not so bad. It provides some immunity to the organism Responsible for malaria.

11.   Recessive genetic disorder.  Blood cannot clot well.  Sex-linked trait.  Mostly affects males. Hemophilia

12. What gender has a greater chance of getting hemophilia?

13.   What are the 4 main blood types? Warm Up

14. Day 4 Notes

15. Blood Type = Multiple Alleles & Codominance  Blood type in humans is controlled by 3 alleles  A, B, and O  A & B are codominant  O is recessive PhenotypeGenotype AAA or AO BBB or BO ABAB only OOO only

17.   A-type can only receive A or O blood  B-type can only receive B or O blood  AB-type can receive A, B, O, AB blood  Universal Receiver  O-type can only receive O blood  Universal Donor Blood type continued…

18.   Could you please help me? I have a question that is NOT a homework question. I am a Junior in High School. "Could a man with type B blood and a woman with type AB produce a child with type O blood?" I think not, because type O is recessive, and the B's seem to be dominant. My cousin thinks yes. Thank you for your help. Problem 1: Is a type O possible in this situation?

19. IMPOSSIBLE

20.   I have been reading your info about inheritance of blood types and I am getting very confused! I am trying to figure out what blood type the father of my son could have since my son and I are both type A. Could you please help? Problem 2: What are the potential blood types of the father of my son?

21.  The father could be:  A. A, AB, B, or OA, AB, B, or O  B. Either A or BEither A or B  C. Either A or OEither A or O
