Transcript With blood type testing, if CLUMPING happens, that

ALL periods should READ “My
Family Pedigree” assignment
posted on Classroom
You will need to complete this assignment by Friday, 1/22. PLEASE complete at home
tonight. You will “TURN IN” via Classrooms using the Classrooms “turn in” button.
Take 5 minutes right now to read and ask each other’s questions about the instructions.

Sorry guys I’m gone today. Both of my sitters are sick, so I’m home being mom.
PLEASE be respectful to Mrs. Tracy. She’s a nurse and can help you with this blood
type information. You know the procedures (ask to go to the restroom, help each
other AND stay on task). NO phones until your class has completed the tutorial I
created for you. Do NOT argue with Mrs. Tracy. She is very knowledgeable and very
sweet. Remember subs have a hard job but YOU can make her day go well 
If you understand what’s going on, PLEASE share YOUR knowledge and teach
others.
Positive feedback will result in a positive result for YOU! Keep that in mind 
Partner Whiteboard learning!
Per pair get one whiteboard, one dry-erase marker and a paper towel
Follow directions on each slide. Take notes when needed and complete practice
problems when asked.
Quiz next period! You can also watch videos on Classrooms for review.
Erase…Make a key for the following...
• In horses, chestnut fur color
is incompletely dominant to
white horse. The
heterozygous genotype
results in a roan horse.
Answer:
• In horses, chestnut fur color
is incompletely dominant to
white horse. The
heterozygous genotype
results in a roan horse.
Chestnut = C
White = W
Roan = CW
Erase..Same key, new question
Chestnut = C
White = W
Roan = CW
• What results if a white horse is bred with a roan horse? Show the
cross as well as the genotypes and phenotypes of the parents and
offspring.
Answer:
Chestnut = C
White = W
Roan = CW
• What results if a white horse is bred with a roan horse? Show the
cross as well as the genotypes and phenotypes of the parents and
offspring.
WW x CW
Chestnut = 0%
White = 50%
Roan = 50%
Erase…new question, same key
Chestnut = C
White = W
Roan = CW
• A breeder has a herd of chestnut and roan horses. Can he bred any of
these horses to make a white horse?
• Show punnett square to prove
Answer…
Chestnut = C
White = W
Roan = CW
• A breeder has a herd of chestnut and roan horses. Can he bred any of
these horses to make a white horse?
• NO white horses can be produced.
• Chestnut (CC) x Roan (CW)
• 50% chestnut
• 50% Roan
• 0% white
Erase…Make a key for the following…
White and black coat fur color
are codominant to each other.
Answer:
White and black coat fur color are
codominant to each other.
White = W
Black = B
Spots =WB
Make a key…
White and black coat fur color are
codominant to each other. Both
colors are dominant to purple
Answer
White and black coat fur color are codominant to
each other. Both colors are dominant to purple
White = W
Black = B
Spots = WB
Purple = a (recessive so it gets a lowercase letter)
Blood types
• https://www.youtube.com/watch?v=ttjn1jVACk8
After the video…
For simplicity, we will only focus
on the four phenotypes:
Type A Blood
Type B Blood
Type AB Blood
Type O Blood
Make a Key…
A-type and B-type blood
are codominant to each
other and are dominant
over O-blood type.
Make a Key…
A-type and B-type blood are
codominant to each other and are
dominant over O-blood type.
•
Type A Blood = IA
•
Type B Blood = IB
•
Type AB Blood = IAIB
•
Type O Blood = i
Don’t let the captiol “I” before the A or B confuse you. It shows you
that there are multiple options that are dominant, so you use capitol
“I” for the dominant and lowercase “i” for the recessive
Write the genotype for Homozygous
A-type.
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
The genotype for Homozygous Atype is…
answer: IA IA
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
Write the genotype for a
Hetero A-type.
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
Write the genotype for a Hetero Atype ?
Answer: IA i
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
Write the genotype for Hetero Btype
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
The genotype for Hetero B-type is
IB i
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
Write the genotype for O-type
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
The genotype for O-type is
ii
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
Predict blood-type for the children…
Homozygous B-type & O-type
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
Homozygous B-type & O-type
answer: IBIB x ii
100% - IBi
100% - Type B Blood
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
AB Type & Hetero A-type
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
AB Type & Hetero A-type
answer: IAIB x IAi
25% - IAIA
25% - IAi
25% - IAIB
25% - IBi
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
Homo B-type & Hetero B-type
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
Homo B-type & Hetero B-type
answer: IBIB x IBi
50% - IBIB
50% - IBi
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
Now…use your new skills to identify ALL the possible
genotypes for the parents.
Mom – B-type
Child – B-type
Dad - ????
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
Parents: IBIB x IBIB  this cross will produce a B-type child.
There are 7 other possible crosses…list them!
Mom – B-type
Child – B-type
Dad - ???
IBIB x IBIB
IBIB x IAIB
IBIB x IBi
IBIB x ii
IBi x IBIB
IBi x IAIB
IBi x IBi
IBi x ii
Dad – O-type
Child – O-type
Child – B-type
Mom- ???
There are TWO possible crosses for this example.
Type A Blood = IA
Type B Blood = IB
Type AB Blood = IAIB
Type O Blood = i
Dad – O-type (ii)
Child – O-type (ii)
Child – B-type (IBi)
Mom- ???
IBIB x ii
IBi x ii
We’ve now have covered ALL
information for your pink packet.
Continue to practice with your pink
practice (BOTH of them!)
Video tutorials on Classrooms.
Don’t forget “My Family Pedigree” assignment needs to be “turn in” via Classrooms by
Friday (aka tomorrow)
th
5
period only
Today you will understand the (+) and (-) about blood, along with the four
phenotypes.
1st – watch video: https://www.youtube.com/watch?v=ttjn1jVACk8
Here’s the summary…
NO
Clumping
means the
sample is
NOT Type A
NO
Clumping
means the
sample is
NOT Rh(+)
EACH four phenotypes can either be Rh+ or RhThis makes 8 different blood types
With blood type testing, if
CLUMPING happens, that means
it’s a match for that type.
Clumping
means the
sample is
Type B
One blood sample is test
with each serums above.
The result of this blood is
Type B(-).
