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

5

• HEREDITY IS BASED OFF OF PROBABILITY (OR CHANCE)
• WHAT GENES WILL YOU GET?
• DOMINANT AND RECESSIVE

6
EXAMPLE
7
LAB

• TAPE
• FILL OUT HYPOTHESIS dont worry about the
  because part
• FILL OUT TABLE
• DRAW A GRAPH
• WRITE CONCLUSION (dont need 1 for each
  hypothesis)

8
TUESDAY NOV. 27TH

  of recessive (bb) genotypes you got from each
  trial

12
INTRODUCTION TO GENETICS

• Yesterday
• Genetics
• Heredity
• Chance

13
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

14
GENES AND ALLELES

• Single gene that codes for eye depth
• BB Bb bb

15

• GG HOMOZYGOUS same alleles
• Homozygous dominant!
• Gg HETEROZYGOUS different alleles
• gg

16
GENOTYPE AND PHENOTYPE

• GENOTYPE genetic makeup
• GG Gg gg
• PHENOTYPE appearance

17
MENDELIAN GENETICS AND PUNNETT SQUARES
18
DOMINANCE RELATIONSHIPS

• Fighting over which allele is going to be
  expressed!
• DOMINANT/RECESSIVE
• CO-DOMINANCE
• INCOMPLETE DOMINANCE

19
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

20
INCOMPLETE DOMINANCE

• Creates an intermediate phenotype.
• The heterozygote is a mixture of the parents.

21

22
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.

23
YOUR TASK

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

24
THURSDAY NOV. 29TH

• WARM-UP
• A 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?

25
FLOW CHART INSTRUCTIONS
26
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

27
FRIDAY!!!!!!! NOV. 30TH

• WARM-UP
• HOLIDAY COUNTDOWN
• 13 MORE DAYS
• WARM-UP
• WHY DID WE USE DETERGENT (IN THE DNA EXTRACTION
  BUFFER) YESTERDAY TO EXTRACT THE DNA? EXPLAIN.

28
TODAY

• PASS OUT QUIZZES
• TURN IN HOMEWORK
• FUN WITH BOOKS!
• ELEPHANT BOOKS, SECT 10.3
• PG. 215-221 sec review 1-4
• QUIZ POINTS

29
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

30
WHAT DID WE SEE?
31
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
