Week 4 Genetic probability
Jan 23 2017
QFD: I have learned over the years that when one’s mind is made up, this diminishes fear. Rosa Parks
Essential question of the day : compare and contrast the terms homozygous dominant, heterozygous and homozygous recessive
This weeks learning objective : HS-LS 4-3 Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait.
1) lecture story of genes alleles and chromosomes
2) group problems co dominance
Hw : read article on Google classroom , highlight important facts .. We will answer questions in class

QFD: Laundry is the only thing that should be separated by color.
-Author Unknown
Essential question of the day : analyze the probability of two random events occurring during meiosis
This weeks learning objective : HS-LS 4-3 Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait.
1) group practice mono and dyhybrid cross

Hw : Finish problems

QFD: I was raised to believe that excellence is the best deterrent to racism or sexism.
-Oprah Winfrey, media proprietor

Essential question of the day : predict the phenotype from the genotype of individuals
This weeks learning objective : HS-LS 4-3 Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait.
1) genotype and phenotype … Mating game

Materials: Other students in class with clothes on
Procedure:
1) Students will draw 25 punnett squares on a separate sheet of paper and title it the observation section
2) Mark a little X in the corner of 1 of the 4 boxes in all punnett squares
3) Students will pair up with 5 members of the opposite sex in the class and trade genotypes.
4) The genotypes are as follows:
Boys –Shoes(ear type)D=dangling dd attached tennis shoes receive DD all other shoes dd
Girls – Shoes Sandals Dd shoes dd
Boys shirt color = blood type white AB blue AO red BO green AA purple BB all others OO
Girls shirt/blouse color = blood type white AB blue AO red BO green AA purple BB all others OO
Boys Pants = Hair color shorts = Bb brown hair pants = BB black hair blue shorts = bb Blonde hair
Girls Pant/skirts = Hair color shorts = Bb brown hair pants = BB black hair blue shorts/skirt = bb Blonde hair
Boys – Eye Color wears a watch = EE ( brown eyes) No watch Ee (green eyes) wears or has a hat or over 3 earrings ee (blue)
Girls– Eye Color wears a watch = EE ( brown eyes) No watch Ee (green eyes) wears or has a hat or over 3 earrings ee (blue)
Boys – Sex type boy/girl wear a belt – X does not wear a belt Y
Girls with 2 ears – X

5) Record the data for each encounter in the punnett squares. Record the boys genotype on top and the girls genotype on the left (3 people X 5 traits = 15 boxes)
6) After you are finished with a member of the opposite sex , record your data using the Xs you marked earlier. For instance you may have a Dangling eared, AB blood type, Blonde haired, green eyed, Boy. Write the combination of traits next to the punnett squares

QFD: He who is not courageous enough to take risks will accomplish nothing in life. ? Muhammad Ali
Essential question of the day : determine the mechanisms for mutation in genes
This weeks learning objective : HS-LS 4-3 Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait.
1) genetic mutations and probability
2) X linked genes

3) problems on Google classroom …Mendel

QFD: Success is to be measured not so much by the position that one has reached in life as by the obstacles which he has overcome while trying to succeed.
-Booker T. Washington, author and politician

Essential question of the day : what would a model of a genetic mutation look like ?

This weeks learning objective : HS-LS 4-3 Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait.
1) Finish all problems by Monday

  1. please can you help me what to do on the last section of the poster and what is the extra credit. thank you.

    • Follow the guidelines in the paper but describe how a variation in species at times favors one type over the other ec was for using a species from Belize
