MONDAY NOV. 26TH

•Please grab your notebook, but return it to the pile before you leave.

•WARM-UP–What do you think genetics is? –What are 3 careers you would use genetics in?

TODAY

•PASS OUT GENETIC BOOKS•WHAT IS GENETICS?•PROBABILITY LAB•TURN COMPBOOKS BACK IN•HOMEWORK DUE THURSDAY –

–READ PAGES 8-12 IN YOUR GENETICS BOOK. ANSWER QUESTIONS 1-9.

WEDNESDAY

•WASL PREP TEST ON EXPERIMENTAL DESIGN.

•GRAPHING – •TERMS –

INTRODUCTION TO GENETICS

•ANSWERING THE QUESTION OF WHY?

•GENETICS – THE STUDY OF HEREDITY AND VARIATION AMOUNG ORGANISMS

•HEREDITY - the transfer of characteristics from parent to offspring through genes

•HEREDITY IS BASED OFF OF PROBABILITY (OR CHANCE)

•WHAT GENES WILL YOU GET? •DOMINANT AND RECESSIVE

EXAMPLE

LAB• TAPE

• FILL OUT HYPOTHESIS – don’t worry about the because part

• FILL OUT TABLE • DRAW A GRAPH• WRITE CONCLUSION – (don’t need 1 for each

hypothesis)

TUESDAY NOV. 27TH

• WARM-UP– From yesterday’s lab, right down the

percentage of recessive (bb) genotypes you got from each trial

• TODAY– Introduction to Genetics Continued– Please return your notebook before

leaving• HOMEWORK DUE THURSDAY

– READ PAGES 8-12 IN YOUR GENETICS BOOK. ANSWER QUESTIONS 1-9.

– Make sure you have a Genetics Book

1st period FOOD DRIVE!

•1 POINT EXTRA CREDIT FOR EACH ITEM YOU BRING IN

•MAX OF 10 POINTS•PERSON THAT BRINGS IN THE

MOST WILL GET A TOTAL OF 15 POINTS

•DUE FRIDAY DEC. 7TH AT THE LATEST!

•BRING A NOTE FROM YOUR 1ST PERIOD TEACHER SAYING YOU DONATED AT LEAST 3 ITEMS AND YOU WILL GET 5 POINTS EXTRA CREDIT

INTRODUCTION TO GENETICS

•Yesterday –Genetics–Heredity–Chance

GENES AND ALLELES

•GENE – there is a single REGION OF DNA that controls the color of a petal

•ALLELE – there many VERSIONS of these genes that can make for different colors

GENES AND ALLELES

Single gene that codes for eye depth

BB Bb bb

•GG – HOMOZYGOUS – same alleles

–Homozygous dominant!

•Gg – HETEROZYGOUS – different alleles

•gg –

GENOTYPE AND PHENOTYPE• GENOTYPE – genetic makeup

GG Gg gg

• PHENOTYPE – appearance

MENDELIAN GENETICS AND PUNNETT SQUARES

DOMINANCE RELATIONSHIPS

• Fighting over which allele is going to be expressed!

• DOMINANT/RECESSIVE

• CO-DOMINANCE

• INCOMPLETE DOMINANCE

CO-DOMINANCE• CAN EXPRESS BOTH PHENOTYPES!!!

– EXAMPLE- BLOOD TYPE– BLOOD TYPE HAS 3 ALLELES- A B

AND i (causes 0 blood type)– i is RECESSIVE TO BOTH A AND B– HOWEVER, A AND B ARE CO-

DOMINANT A iB AB Bi

i Ai O

INCOMPLETE DOMINANCE•Creates an intermediate

phenotype. •The heterozygote is a mixture of

the parents.

GOING BEYOND

•Multiple Alleles – More than two alleles control the phenotype.

EX -Coat color of rabbits.

•Polygenic traits – Several genes control the trait. Ex-Skin color in humans.

YOUR TASK

• COMPLETE THE PRACTICE PROBLEMS– MAKE SURE TO DO ALL WORK IN YOUR

COMPBOOKS – DON’T WRITE ON SHEET!– FOLLOW DIRECTIONS FOR FULL POINTS

• HOMEWORK FOR THURSDAY– MAKE SURE YOU HAVE YOUR GENETICS

BOOK SIGNED UP BEFORE YOU LEAVE TODAY

• TOMORROW– WASL PROMPT TEST– WORTH POINTS– TURN IN CROSSWORDS

THURSDAY NOV. 29TH

WARM-UPA RED FLOWER AND AN YELLOW FLOWER CROSS. WHAT TYPE OF

DOMINANCE IS BEING DISPLAYED FOR EACH OF THE FOLLOWING POSSIBLE

OUTCOMES?

1. IF A RED FLOWER WITH A YELLOW STRIPE IS PRODUCED?2. IF AN ORANGE FLOWER IS PRODUCED?3. IF A YELLOW FLOWER IS PRODUCED?

FLOW CHART INSTRUCTIONS

TODAY

•TURN IN HOMEWORK!•DNA EXTRACTION LAB

–PROCEDURES ARE VERY SENSATIVE!

–WORK IN PAIRS–WHEN DONE READ INFORMATION ON BACK AND ANSWER QUESTIONS ON POST LAB

FRIDAY!!!!!!! NOV. 30TH

•WARM-UP– HOLIDAY COUNTDOWN

13 MORE DAYSWARM-UPWHY DID WE USE DETERGENT (IN THE DNA EXTRACTION BUFFER) YESTERDAY TO EXTRACT THE DNA? EXPLAIN.

TODAY

•PASS OUT QUIZZES•TURN IN HOMEWORK•FUN WITH BOOKS!

–ELEPHANT BOOKS, SECT 10.3•PG. 215-221 sec review #1-4

•QUIZ POINTS

QUIZ POINTS

• IF YOU GOT BELOW A 15/20 CAN POSSIBLY GET UP TO A 15

• DRAW A DIAGRAM OF OSMOSIS AND PHOTOSYNTHESIS– LABEL WITH 5 VOCAB WORDS EACH– MUST BE ACCURATE (EX.

CONCENTRATION OF MOLECULES FOR OSMOSIS)

– ADD COLOR– MUST BE PRESENTABLE

WHAT DID WE SEE?

WHY CAN WE “SEE” THIS MOLECULE?

• LARGEST MACROMOLECULE KNOWN

• THERE ARE ABOUT 2M OF DNA IN EACH OF YOUR CELLS

• IF ALL THE DNA IN YOUR BODY WAS PUT END TO END, IT WOULD REACH TO THE SUN AND BACK OVER 600 TIMES

• HUMAN DNA IS 98 PERCENT IDENTICAL TO CHIMPANZEE DNA
