GENOTYPE VS. PHENOTYPE

Aa, Bb, cc, dD, eE, FF, Gg, Hh, ii, JJ, kK, ll, MM….OH MY!!!

April 2, 2013

BY THE END OF THE DAY… Achievers on the ROAD to college will know the difference between a phenotype and a genotype.

Achievers on the ROAD to college will be able to predict a phenotype using a given genotype.

Achievers on the ROAD to college will be able to answer our question of the day!!

QUESTION OF THE DAY!! How is the way that we look (phenotype) related to our DNA (genotype)?

How do we get from a strand of DNA to a blonde haired, green eyed Ms. O’Hara?

HOW ORGANISMS LOOK VS. HOW THEIR GENES LOOK?

The alleles for the dimple trait are written above each child below.

DD Dd dDdd

Which kids have dimples and which ones don’t?

GENOTYPE The way the (1)alleles are written is called its genotype.

DD, Dd, dd are all genotypes for dimples

(2)AA, Aa, AABb are all examples of genotypes

PHENOTYPE What an organism (3)looks like It is the genotype expressed in a way we can observe.

In our example, dimples or no dimples give the phenotype

(4)Tall, green seeds, brown hair are all examples of phenotypes

Phenotype = Physical

There are 2 dimple phenotypes:

Dimples No Dimples

BUT. There are 4 dimple genotypes.

Big LipsPHENOTYPE

HOMOZYGOUS Organism that has (5)two identical alleles for a given trait

AA, aa, BB, bb are all examples ((6)Both letters are either capital or lowercase)

HETEROZYGOUS Organism that has two (7)different alleles for the same trait

Called a (8)hybrid for that trait Aa, Bb are examples (one letter is a capital and one is lowercase)

ROAD CHECK Remind me, what does phenotype mean?

What does genotype mean?

GENOTYPE AND PHENOTYPE

With genotype BB, what phenotype would we see?

BB or Bb=brown eyesbb= blue eyes

Brown eyes

GENOTYPE AND PHENOTYPE

With genotype Ss, what phenotype would we see?

SS or Ss= brown skinss=white skin

Brown skin

GENOTYPE AND PHENOTYPE

LL or Ll=big lipsll=small lips

What would the genotype be for big

lips??LL or Ll

GENOTYPE AND PHENOTYPE

SS or Ss=brown skinss=white skin

With phenotype white skin, what genotype(s) could we see?

ss

GENOTYPE AND PHENOTYPE

DD or Dd= dimplesdd= no dimples

If you notice your little brother has no dimples, what

must his genotype(s) be??dd

AGENDA1. Bell Ringer2. College3. Notes4. Question of the Day5. Paper Pets!

QUESTION OF THE DAY!! How is the way that we look (phenotype) related to our DNA (genotype)?

How do we get from a strand of DNA to a black haired, green eyes? BB or Bb = brown hair, bb = blonde hair

GG or Gg = green eyes, gg = blue eyes

AGENDA1. Bell Ringer2. College3. Notes4. Question of the Day5. Paper Pets!

INDEPENDENT PRACTICE

You are going to create a Paper Pet using a genotype that is given to you.

Each person in your group will have a different genotype (SO DON’T TRY TO COLOR EXACTLY WHAT YOUR NEIGHBOR DOES )

INDEPENDENT PRACTICE CONTINUED… You are going to use the chart on your paper to help you figure out what phenotype corresponds to your given genotype

You will then draw or color those characteristics on your paper pet.

ON THE BACK OF YOUR PAPER PET:

My paper pet had these phenotypes:
