Blood Genetics & Codominance Notes

Codominance Codominance – some genes have two alleles that are the same strength -- causes a new trait.

List the different blood type phenotypes: These are known as _____________________________

List the different blood type phenotypes: A AB B O These are known as antigens

What blood type accepts what? B accepts ____, _____ A accepts ____, _____ Everyone accepts ____ O accepts ____ AB accepts ____, ____, ____, ______

What blood type accepts what? B accepts B, O A accepts A, O Everyone accepts O O accepts O AB accepts A, B, AB & O

Why would it be nice to have AB blood? __________________________________________________________ __________________________________________________________ __________________________________________________________

Phenotype Genotype Type A Type B Type AB Type O

Phenotype Genotype Type A IAIA <- Homozygous IAi <- Heterozygous Type B Type AB Type O

Phenotype Genotype Type A IAIA IAi Type B IBIB <- Homozygous IBi <- Heterozygous Type AB Type O

Phenotype Genotype Type A IAIA IAi Type B IBIB IBi Type AB IAIB Type O ii

Phenotype Genotype Type A IAIA IAi Type B IBIB IBi Type AB IAIB Type O ii <- no antigens

Work on these independently, but be ready to share! Practice Sets Work on these independently, but be ready to share!

Blood Typing Lab Tomorrow!

Update Data Folder & Pass Back Papers I need 4 volunteers to help with passing out papers!  Take out Data Folder – you should have your plus/delta sheet for “Cells and Cell Division”. Update data folder with (printed) handouts in your ISN, filed under the tab “Cells and Cell Division.” Reminder: Monsters Inc. Genetics due Friday! Reminder: H&G Project Part 1 due Monday!!!!!****
