1 Exploring Mendelian Genetics http://www.eslkidstuff.com/images/tallshort.gif http://sps.k12.ar.us/massengale/genetics%20tutorial.htm

2 GENES are more complicated than Mendel thought ____________________________ the ________________________. = ________________________ Genes ________ the ______ for development, but how plan unfolds also _______ on ______________conditions.

3 GENES are more complicated than Mendel thought Some traits have ____________ allele __________ = ____________________ EX: blood type Allele choices ___ ___ ___

4 GENES are more complicated than MENDEL thought Some traits are determined by ____________________________ = __________________ EX: human height. intelligence, skin & eye color http://www.bcps.org/offices/lis/models/life/images/grow.JPG

5 GENES are more complicated than MENDEL thought Traits determined by ____________ _________ have _____ “___________” phenotypes http://www.newtonswindow.com/problem-solving.htm There aren’t just SMART people and DUMB people…. there is a ________________ of intelligences in-between

6 GENES are more complicated than MENDEL thought KINDS OF DOMINANCE ____________________

7 COMPLETE DOMINANCE __________ allele _______ the ___________ one PATTERN ? ____________ allele ________ in a _____ratio in the ____ generation http://www.emc.maricopa.edu/faculty/farabee/BIOBK/BioBookTOC.html

8 INCOMPLETE DOMINANCE __________ expected _____ ratio in F 2 generation _____________ organisms with one dominant and one recessive allele show a _________ in-between trait Image modified from: http://www.emc.maricopa.edu/faculty/farabee/BIOBK/BioBookTOC.html

9 CO-DOMINANCE _______ traits are expressed at ___________ (_____________________) in heterozygote A ________HORSE has ______________ hair and __________ hair side by side

10 CO-DOMINANCE Both traits are expressed together (NO BLENDING) in heterozygote Persons with an A allele AND a B allele have blood type AB

11 BLOOD TYPES have more than 2 allele choices = _________________________ The pattern of sugars that is attached is determined by genes Allele choices are: _____________

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

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

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

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

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

17 BLOOD TYPES YOU ARE DIFFERENT! IMMUNE SYSTEM ATTACKS! Body images modified from: http://www.new-fitness.com/images/body_shapes.jpg YOU DON’T HAVE ANYTHING I DON’T HAVE! DONOR BLOOD

18 BLOOD TYPES YOU ARE DIFFERENT! IMMUNE SYSTEM ATTACKS! Body images modified from: http://www.new-fitness.com/images/body_shapes.jpg YOU DON’T HAVE ANYTHING I DON’T HAVE! DONOR BLOOD

19 BLOOD TYPES YOU ARE DIFFERENT! IMMUNE SYSTEM ATTACKS! Body images modified from: http://www.new-fitness.com/images/body_shapes.jpg YOU’RE LIKE ME! DONOR BLOOD

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

21 BLOOD TYPES Body image modified from: http://www.new-fitness.com/images/body_shapes.jpg ______ can RECEIVE FROM EVERY BLOOD TYPE = ________________________
