Homework for tonight -  All classes: 

Answer everything on the first side of Bikini Bottom Genetics worksheet. 

Monday, February 12, 2018

All students: Answer all questions (that you did not answer in class on Friday or today) from the handout in class given out to most students on Friday.  If you need information, look at the SEPUP book, Activity 60.  To get to the SEPUP book, use the first link in the list to the right of this information. ------>

For those several students absent today, you can catch up on today's work by copying the new Vocabulary at the bottom of this page, and by reading Activity 60: Mendel, First Geneticist from the SEPUP book.  To get to the SEPUP book, use the first link in the list to the right of this information. ------>. Then, answer the questions on the Notes given out on Friday:  


Stopping to Think Questions for: Mendel, First Geneticist



  1. Name ________________   Per. _____ Date __





    Stopping to Think Questions for: Mendel, First Geneticist
    1. What personal qualities do you think Mendel must have had that helped him in his work? 





  1. a. What were the advantages for Mendel in using pea plants for his breeding investigations?


     b. Why did Mendel perform so many crosses for the same characteristics?


  1. Explain how the model in Activity 59, “Gene Combo,” works exactly like Mendel’s explanation for his results with pea plants.


Analysis Questions on p. D-31 to 34:
1.  Bas
ed on Mendel’s results, which trait for each pea characteristic is dominant? In your science notebook make a table like the one below. In your table, list the dominant and recessive traits for each characteristic.



2.a. Calculate to the hundredths place the ratio of dominant to recessive for each characteristic in the third generation. Record the ratio for each characteristic in the table you prepared for Question 1.



    b. Why are the ratios not exactly 3:1?





3.  Look at the pie chart on the previous page, which shows the ratio of green-seeded and yellow-seeded offspring. Explain why a 1:3 ratio of green-seeded plants to yellow-seeded plants is the same as a fraction of green-seeded plants.





4.  Mendel performed his experiments on more characteristics than the four shown in the circle graph, “Seed color ratios”, shown above on the previous page.   Why was it important for him to look at more than one characteristic?






5.  Reflection:  People often think of mathematics as important to physics and chemistry, but not to life science (biology). What is your opinion?





Vocab: (copy definitions into your vocab section):
Also: Allele , Dominant , Recessive.
Carrier - An organism that carries and transmits a disease but has no symptoms of the disease. Genetic diseases are caused by a recessive gene. If an organism is heterozygous (has 1 dominant and 1 recessive gene), then the condition is hidden. The organism can, however, transmit the recessive allele to their offspring. If the other parent also gives a recessive allele for the condition, then their offspring will have the disease.

Heterozygous - an organism that has more than 1 kind of allele for a characteristic. (ex: Bb)
Homozygous - an organism that has only one kind of allele for a characteristic. (ex: BB or bb)
Punnett Square - diagram to show the likelihood of each outcome of a breeding experiment with known parent genes for a trait.

Tonight's Homework is a combination of answering Analysis Questions from our lesson, Gene Combo,  and copying vocab terms into your book..  

1. Answer Analysis Questions on p. D-29 to 30, but if you were assigned to answer only certain questions in Period 2 or 3, then you need only answer the question(s) you were assigned.  I have re-typed the Analysis Questions at the bottom of this entry

2. (All Classes): Copy the following Vocab into your vocab section. You'll be Quizzed about these on Friday:
Vocab: (copy vocab words and definitions into your vocab section):

Allele - a variant or version, on a gene, of a characteristic.
Characteristic - quality or property that defines or describes someone or something.
Dominant - version of gene that shows with only 1 copy of an allele, or version of a gene. Always shown with a capital letter.
Fertilization - union of a sperm cell and an egg cell to form a zygote.
Probability - The likelihood that a particular event will occur; allows us to predict how likely each result is, but not the actual sets of results obtained.
random - equally likely to be chosen; there is no bias.

Recessive- hidden trait; a genetic trait that is not shown in an heterozygous individual. Always shown with a lower case letter. Ex: Albinism

Analysis Questions on p. D-29 to 30: 
1. What is the ratio of blue-tailed to orange-tailed critter pups? Use the class data to answer this question: 

a. Divide the number of blue-tailed offspring by the number of orange-tailed offspring. 

     ratio of tail colors = number of blue-tailed offspring 
                                      number of orange-tailed offspring 

b. Round this value to the nearest whole number. Then express it as a ratio by writing it like this: 

----------------------------------  : 1
                    (whole number)                                 


c. Express this ratio as a pair of fractions, so that you can use them to complete the following sentence: 
“About *______ of the offspring have blue tails, and about  *______ of the offspring have orange tails.”  
         * = Hint: "one- _________"

d. Explain why the class obtained such a large ratio. For example, why isn’t the ratio of blue to orange tails 1:1, that is, ½  blue and ½ 
 orange?

2. You and your partner are about to toss two coins 100 times. Predict about how many times the outcome would be: 
     a. heads–heads        (Note: these are not multiple choice 
     b. heads–tails            options: Answer each one!)
     c. tails–heads 
     d. tails–tails 

3. How sure are you that you will get exactly the results you predicted for Question 2? Explain your answer. 

4. Look back at Activity 58, “Creature Features.” Do the results of the cointossing model match the Generation Three critter data? Explain. 

5. What are the advantages and disadvantages of using coin tosses in a model for how genes are passed from parents to offspring? Explain. 

6. Review the rules of genetics that the class developed in the last activity. Which ones make this model work? 

7. Write your own definition of the phrase dominant trait as it is used in genetics. Hint: Does it mean that every time any pair of f critters mates, most of the offspring will have blue tails? Why or why not?

Friday, January 26, 2018

The following vocab must be copied into your science notebook VOCAB section by Wednesday morning: 

Vocab: (copy vocab words into your science notes and copy definitions into your vocab section):

Asexual reproduction- organism divides to make 2 copies of the parent, without gametes uniting. Single cell organisms (bacteria, algae & amoeba) split into clones; multi-cellular organisms such as Hydra can bud; strawberry plants use runners.
cell - smallest unit of structure & function of all organisms; cells are enclosed by a membrane.
cell division -cell splits from 1 to make 2, then 4, and so on, to make many.
clone - offspring produced by asexual reproduction (natural or artificial); new cell inherits all of its traits from a single parent.
DNA- molecule 'string' of genetic material that codes for organism traits.
Fertilization - union of a sperm cell and an egg cell to form a zygote.
Gametes - sex cells. Sperm is a male sex cell; an Egg is a female sex cell.
mutation - random copying error in DNA. Offspring gets a different trait than parent(s) cells.
offspring - new organism produced by a living thing.
sexual reproduction - When a sperm cell unites with an egg cell to produce offspring that inherit traits from both parents.


Tuesday, January 23, 2018

Per. 2 - Finish the height bar on our bar graph. 

Pers. 3, 4, 6, 7 - Research a human characteristic (NOT one of the ones that we investigated in class) and write a sentence about the characteristic and it's traits, or versions, in the skinny column of yesterday's note package.

Getting StartedHow do characteristics relate to traits?_______________________

____________________________________________________________________

You can use the vocab definitions from class today, such as:
o     Characteristic - an observable or measurable feature of an organism and may be caused by one gene or many genes. Ex: eye color.
o    Traits - characteristics that can occur in different versions.

Homework
1. For Friday's test, Answer all questions you can on the study guide. I encourage you to work with your study buddy.  

2. Please copy the following vocab terms into the vocab section of your science notebook Do not ignore writing one of the terms just because it's in gray text, because I sometimes can not control some text colors on the blog.  Check before you start each term to see if you already put that one in your vocab section (so you don't accidentally write it twice): 


Bacteria - single celled organisms that do not have a nucleus or other membrane-bound organelles. 

Cells- the basic unit of structure and function that makes up all living organisms. Enclosed in a membrane.
Cell Membrane - structure that separates the cell from its external environment.
Cell Theory (a/k/a "Cell Principle") - All living organisms are made up of cells. New cells are made from existing cells.
Cytoplasm - material that fills much of the inside of cells.
Germ Theory- each infectious disease is caused by a certain species of microbe.
Hereditary - diseases caused by cells that don't work right, and pass the defective information along when they reproduce. (more later -leave space)
Infectious - can be spread from one person to another.
Multicellular - organism made of more than 1 cell.
Nuclear Membrane - structure that separates the nucleus from the rest of the cell.
Nucleus - control center of the cell, this contains DNA (leave space, more info later).

Organelles - cell structures, often surrounded by a separate membrane, that perform a specific function.
