Assignment: Biology of Genetics Paper
Explain how Mendel’s interpretation of his pea plant experiments would have changed if he did not use pure breeding, homozygous genotypes in his P1 generation, but instead used heterozygotes.
Being double-jointed is a dominant trait found in humans and is designated here by the letter D. The recessive allele is designated by the letter d. A homozygous dominant mother and a homozygous recessive father want to have children. What percentage of their kids would be predicted to be heterozygotes, homozygous dominant, and homozygous recessive? What is the only genotype of two parents that would ensure that their offspring would not be double-jointed?

A man with AB blood and a woman with AB blood have a child. Is it possible for them to have a child with O blood? What are the possible blood types of their offspring and what is the expected percentage of each?
Cystic fibrosis is an autosomal recessive disease characterized by two copies of a mutated CFTR gene. If one in 100 (hypothetical scenario, not reality) people in the United States have cystic fibrosis, calculate the p and q frequency for the normal allele (p) and the mutated allele (q). Based on those calculations, what percentage of individuals would be expected to be homozygous dominant?
Red-green colorblindness is a recessive trait that is located on the X chromosome. A woman named Eve, who is not colorblind, has a mother that is not colorblind and is not a carrier, and a father who is colorblind. Predict the probability of Adam and Eve having a daughter colorblind, a daughter having normal vision, a son being colorblind, and a son having normal vision. Explain your reasoning.
One strand of a single DNA helix is labeled red while the other strand of the same DNA helix is labeled blue. This double helix DNA is replicated through the process of semi-conservative replication. Note that a completely newly synthesized strand of DNA will be white. After three rounds of DNA replication, how many all-white DNA (both strands are white) will there be? Explain your reasoning.
Transcribe and translate the following sequence of DNA: ATGAAGTTACCC. There is a mutation that resulted in the following sequence: ATGAAATTACC. Predict how this mutation would impact the product of translation.
Which, if any, of the following sequences cannot exist for an mRNA. Explain your answer
A. UUUUUU
B. AAAAAA
C. CCCCCC
D. UAUAUA
E. GAGAGA
Hypothetically, a cell has DNA that weighs 10 picograms. This cell goes through the S phase and is about to undergo mitosis. How much does the DNA of this cell weigh now? How much would the DNA of the two cells produced at the end of mitosis weigh? Explain your reasoning.
A cell that has a diploid number of 24 goes through meiosis. How many chromosomes would be in each cell after Meiosis II is completed? Would these cells be haploid or diploid? How many cells would be expected at the end of Meiosis II? Explain.
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. Assignment: Biology of Genetics Paper
