Quiz on Traits, Mendel, and Punnett Squares

1)Silently review notes for 5 minutes.2)Go to Haiku 2/21/14 page. Download today’s

PowerPoint. 3)Read each question THREE times before

writing your answer. Look for key words and context clues in the questions, answers, and/or pictures.

4)Make sure you have answered each question with the required information. Check answers when finished.

5)When done sit quietly and …• Read over the Genetics Projects linked to

today’s PowerPoint. • Choose one project to complete. Write down

any questions that you have about the project you have chosen.

Question #1

A characteristic that an organism can pass on to its offspring through its genes or can be developed or learned.

Question #2

A trait which is developed or learned during your life.

Question #3

A trait which you are born with.

Question #4

Blue eyes is an example of a(an)…

Question #5

1. Draw a Punnett square.2. Then label where the male and female genotypes are written

Question #6

In pea plants, green pod color (G) is dominant over yellow pod color (g). Create a Punnett square of a cross between a hybrid male plant with green pods (Gg) and a female plant with yellow pods (gg).

Question #7

In pea plants, yellow seed color (Y) is dominant over green seed peas (y). Create a Punnett square of a cross between a male and female plant both heterozygous for yellow seed color (Yy).

Question #8

What is the probability that the offspring of this cross will be Yy?

Y yY YY Yyy Yy yy

Question #9

What is the probability that the offspring of this cross will have green seeds?

Y yY YY Yyy Yy yy

Question #10

In pea plants, round peas (R) are dominant over wrinkled peas (r). Create a Punnett square of a cross between a female male plant homozygous for round peas (RR) and a male plant homozygous for wrinkled peas (rr).

Question #11

What is the probability that the offspring of this cross will be Rr?

R Rr Rr Rrr Rr Rr

Question #12

In humans, brown eyes (B) are dominant over blue (b). A brown-eyed man marries a blue-eyed woman and they have three children, two of whom are brown-eyed and one of whom is blue-eyed. Use the correct Punnett square to show the genotypes of the parents and the children.

Question #13

The different forms of a gene.

Question #14

The Father of Genetics

Question #15

Having two identical alleles for a trait.

Question #16

Give an example of a homozygous dominant genotype.

Question #17

An organism’s physical appearance, or visible traits. “What you see”

Question #18

An allele whose trait shows up in the organism with only one copy.

Question #19

Having two different alleles for a trait.

Question #20

Give an example of a heterozygous genotype.

Question #21

An allele whose trait shows up in the organism only when two identical copies of the allele are present.

Question #22

An organism’s genetic makeup. “The genes it has”

Question #23

The passing of genes from parents to offspring.

Question #24

A pet store owner has three guinea pigs: 1. Purebred Black2. Hybrid Black3. purebred brown

If the store owner wants to get more brown guinea pigs, which two should he breed?

What is the probability of getting a brown guinea pig from this cross?

Question #25

Gregor Mendel was from…

Evening Assignment

This weekend… Choose the genetic project you would like to complete.

Write down any questions that you might have if you do not understand how to do the project you have chosen.

Genetics Projects

Selective Breeding vs. Genetic ModificationCorn is one of the most manipulated crops. Create a Presentation or Poster comparing traditional selective breeding vs. genetic modification (GMO). Explain the two methods and then show some specific corn varieties/cultivars that were created with each method and how.

Genes associated with inherited traitsWe learned about several common inherited human traits. Pick at least 10 traits to research and which genes control these traits. Include pictures of the traits phenotypes as part of your presentation. You may complete as a Word document or presentation.

Inheritance of Eye ColorCreate a Powerpoint presentation about the genetics of eye color. Include information about the different types of eye color, any genes that are associated with eye color, and how eye color is inherited. In your final slide, explain how YOU inherited your eye color.

Myths of Human GeneticsDr. John McDonald from the University of Delaware has written that many of the inherited traits students learn in genetics class AREN’T really inherited in a simple dominant vs. recessive pattern that is taught. Create a Powerpoint to review his arguments and compare it to what MOST genetics students learn.

Meiosis GameCreate a game to help students learn the steps of meiosis. Students must answer questions about chromosomes, genes, DNA, and meiosis to advance through the stages of meiosis I and meiosis II. You win when you reach the final gamete stage.

Plant GeneticsGrow two different species of plants and create a digital comparison of their phenotype similarities and differences (appearance, size, growth rate, etc). Then research the genetics of the two species summarizing what you find. Include the number of chromosomes and genome size

Expanded Traits SurveyCreate YOUR OWN survey of ten inherited traits. You may use 5 of the ones we did but must include 5 new ones. Sample at least 50 people. Write up your finds as a Research Investigation Article – but with more detailed and thorough sections than we did as a class.

Genetic DisordersCreate a Presentation about a specific genetic disorder. You must include the following information about that disorder: description, signs/symptoms, how it’s inherited or acquired, genes affected (including the mutation if known), incidence, and treatment.

GMOs in the NewsFarmers and scientists use GMOs to create better crops. Write a news article picking a specific GMO and discuss the process, the benefits, and risks of using that GMO

History of GeneticsCreate a timeline about the history of genetic knowledge starting with ancient times (ex. Biblical times) through the present. You must have at least 15 descriptions along the timeline.

Selective Breeding in DogsDog Breeders use selective breeding to improve dog breed. Create a brochure to explain the selective breeding process and use specific examples to show how breeders have gotten new dog breeds.

Pedigree AnalysisCreate a pedigree of at least three generations using a single inherited trait. You must use a REAL family either your own or one you research. Include a Punnett square from each generation to show how that trait was inherited (3 total)

Choose ONE of the following projects to do as a summative MAJOR assessment for the Genetics Unit. Do detailed, quality work to get full credit.
