GENES are more complicated than Mendel thought Some traits have choices ______ MORE than 2 allele _____ EX: blood type B ___ A ___ O Allele choices ___

REMEMBER Membrane proteins with _______ sugars attached that help cells recognize self = _______ GLYCOPROTEINS http: //www. mannanw. com/super-sugars. htm

BLOOD TYPES The pattern of sugars on glycoproteins is determined by genes and give your blood type

BLOOD TYPES An A allele tells the cell to put “A” glycoproteins on its surface

BLOOD TYPES A B allele tells the cell to put a different “B” glycoprotein on its surface

A and B are CO-DOMINANT A cell with BOTH an A and a B allele has BOTH “A” and “B” glycoproteins on its surface

BLOOD TYPES An O allele tells the cell NOT to put anything on the surface

BLOOD TYPES & ALLELES GENOTYPE AA AO BB BO OO AB PHENOTYPE (BLOOD TYPE) A A B B O AB

DONOR BLOOD A and AB see A as “like me” Body images modified from: http: //www. new-fitness. com/images/body_shapes. jpg B and O see A as Different! IMMUNE SYSTEM ATTACKS!

DONOR BLOOD B and AB see B as “like me” Body images modified from: http: //www. new-fitness. com/images/body_shapes. jpg A and O see B as Different! IMMUNE SYSTEM ATTACKS!

DONOR BLOOD O can donate to ____ EVERY BLOOD TYPE = ___________ UNIVERSAL DONOR Nothing on surface to recognize as “NOT SELF” YOU DON’T HAVE ANYTHING I DON’T HAVE! Body images modified from: http: //www. new-fitness. com/images/body_shapes. jpg

OTHER BLOOD TYPES __________ IF: NO PROBLEMS Rh+ MOM is _____ & BABY is _____ Rh+ Image modified from: http: //www. wsd 1. org/lessonplans/images/Body. gif MOM is _____ Rh+ & BABY is ____ Rh-

PROBLEM IF: Can be a ______ Mom is _____ Rh- Baby is _____ Rh+ 1 st baby OK but few baby cells entering mom’s bloodstream put mom’s immune system on alert for + cells. Next + baby, mom’s immune system can attack baby as it is growing Mom given shot after 1 st birth prevents this Image modified from: http: //www. wsd 1. org/lessonplans/images/Body. gif
