Mendel and the Gene Idea Lab Report.

Lab: Mendel and the Gene Idea Human genetics involves the inheritance of specific traits. These traits may involve physical, mental or physiological characteristics unique to a particular individual and his or her relatives. Why do some people look like their parent or grandparents? How is it possible for a blond-haired child to have two brown-haired parents? Why do brothers in one family resemble each other and in another family have no resemblance? These questions can be answered by a study of heredity. The study of heredity is called genetics. What is your phenotype? Phenotype is an observable physical characteristic, such as your hair color, eye color, height, skin color etc.

Your phenotype is the observable result of your genotype. Genotype is your genetic make-up. It is the combination of alleles of a gene that will determine your physical traits, your phenotype. Each gene can have a pair or a series of alleles. For example, there are many alleles for eye color: blue; brown; green; grey; hazel etc. Gene’s for which an individual has two different alleles is termed heterozygous; whereas gene’s for which an individual has two identical alleles is termed homozygous. Part I –What is your phenotype? In this section, you will be identifying your phenotype for three specific human traits. After each description of the trait, determine your phenotype for that specific trait. Record your observations in the space provided below. A. Tongue Rolling Ability The ability to roll the tongue into a “U” shape when the tongue is extended from the mouth is a dominant human trait. “Nonrollers” can do no more than produce a slight downward curve of the tongue. A person can either roll the tongue easily or not at all. tongue rolling 1. Are you a tongue-roller? 2. Can you tell whether the tongue-rollers are heterozygous or homozygous for tongue rolling? Explain why or why not. B. Attached Ear Lobes In most people, the ear lobes hang free or are unattached. This is a dominant trait. When a person is homozygous for the recessive trait, you will observe earlobes attached directly to the side of the head or jaw line. earlobes 3. Are your earlobes attached? 4. What could be your genotype? C. Bent Little Finger A dominant gene causes the last joint of the little finger to bend inward toward the fourth finger. Lay both of your hands flat on the table, relax the muscles, and observe whether you have a straight or bent little finger. 5. Is your little finger bent? 6. What is your genotype? D. Eye Color Eye color is controlled by many different genes. eye color 7. What color are your eyes? 8. Why is it harder to know your genotype? E. Hair Straight hair, HH, is a dominant trait while curly is the recessive trait, hh. The heterozygote Hh actually has wavy hair. hair 9. Is your hair straight, curly or wavy? 10. What does that tell you about your genotype? PART II– Making a Pedigree Pick one of the traits from above and do a pedigree chart from your family members. A chart will have circles for females and squares for males. If the family member has the trait, color that in. If not, leave open. See figure 19.16a in your book for an example of a pedigree. You can make a pedigree in WORD or PowerPoint. Go to “Insert” “Shapes” and choose a circle (female) and a square (male). You can color it in by changing the “shape fill” color. You can connect the shapes with lines. Make sure you have a key to your answers. If your family isn’t available, feel free to use a hypothetical family or even your dog, horse (etc) if you know their breeding. You can hand draw your pedigree and take a picture or scan it if you would like. You can also do a pedigree chart on someone else- or even a pet! Be sure to describe in words what your chart shows. Here is an example of a pedigree chart. pedigree.jpg Blog: Do it on lynch syndrome and make 500 words and cite sources in apa There are so many different diseases that are caused by mistakes in the genes. Sometimes there is a simple mutation, or change in one DNA base that results in a change in an amino acid. Other mutations may involve deletion of many DNA bases and sometimes additional DNA may be inserted into a gene. For this week: Choose a genetic diseases from the list below. Go to Medline Plus and find some information on your disease. Include: A brief summary frequency Causes Inheritance Treatment

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.

Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.

Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.

The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.

ADDITIONAL INSTRUCTIONS FOR THE CLASS

Discussion Questions (DQ)

Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words.
Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source.
One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words.
I encourage you to incorporate the readings from the week (as applicable) into your responses.

Weekly Participation

Your initial responses to the mandatory DQ do not count toward participation and are graded separately.
In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies.
Participation posts do not require a scholarly source/citation (unless you cite someone else’s work).
Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week.

APA Format and Writing Quality

Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required).
Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation.
I highly recommend using the APA Publication Manual, 6th edition.

Use of Direct Quotes

I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly.
As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content.
It is best to paraphrase content and cite your source.

LopesWrite Policy

For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me.
Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes.
Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own?
Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score.

Late Policy

The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies.
Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances.
If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect.
I do not accept assignments that are two or more weeks late unless we have worked out an extension.
As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading.

Communication

Communication is so very important. There are multiple ways to communicate with me:
Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class.
Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours. Mendel and the Gene Idea Lab Report.
