Assignment: Mendelian Genetics Lab Report
Assignment: Mendelian Genetics Lab Report
Mendelian Genetics Introduction to Biology | Minneapolis Community and Technical College Instructions For this lab activity, you’ll complete ten exercises by drawing Punnett squares. You’re required to show your work for all of these exercises by drawing Punnett square(s)—whenever you draw a Punnett square, follow the five steps listed below. I posted a video on D2L that walks through examples (showing my work!) a monohybrid cross, test cross, codominant cross, and dihybrid cross. 1. Write out the genotypes of the individuals being crossed (this will either be the genotypes of the parental generation or the F1 generation, whichever the question asks for). 2. Determine the genotypes of all the possible gametes that the parents can produce. Gametes are haploid, so only one letter per trait. 3. Construct a Punnett square. The Punnett square is a diagram to visualize and predict outcomes of genetic crosses. The labels of the rows and columns represent the genotypes of the gametes of the first and second parent, respectively. Then, fill in the Punnett square to determine the genotypes of the offspring. 4. Write out the genotypes of the offspring (percent, ratio, and number) 5. Determine the phenotypes of the offspring (percent, ratio, and number) Write your answers by hand and submit a scanned PDF or separate photos (ex. taken with your smartphone) of each page to D2L.
he principles of Mendelian inheritance were named for and first derived by Gregor Johann Mendel,[3] a nineteenth-century Moravian monk who formulated his ideas after conducting simple hybridisation experiments with pea plants (Pisum sativum) he had planted in the garden of his monastery.[4] Between 1856 and 1863, Mendel cultivated and tested some 5,000 pea plants. From these experiments, he induced two generalizations which later became known as Mendel’s Principles of Heredity or Mendelian inheritance. He described his experiments in a two-part paper, Versuche über Pflanzen-Hybriden (Experiments on Plant Hybridization),[5] that he presented to the Natural History Society of Brno on 8 February and 8 March 1865, and which was published in 1866.
Mendel’s results were largely ignored by the vast majority. Although they were not completely unknown to biologists of the time, they were not seen as generally applicable, even by Mendel himself, who thought they only applied to certain categories of species or traits. A major block to understanding their significance was the importance attached by 19th-century biologists to the apparent blending of many inherited traits in the overall appearance of the progeny, now known to be due to multi-gene interactions, in contrast to the organ-specific binary characters studied by Mendel.[4] In 1900, however, his work was “re-discovered” by three European scientists, Hugo de Vries, Carl Correns, and Erich von Tschermak. The exact nature of the “re-discovery” has been debated: De Vries published first on the subject, mentioning Mendel in a footnote, while Correns pointed out Mendel’s priority after having read De Vries’ paper and realizing that he himself did not have priority. De Vries may not have acknowledged truthfully how much of his knowledge of the laws came from his own work and how much came only after reading Mendel’s paper. Later scholars have accused Von Tschermak of not truly understanding the results at all.[4][10][11][12]
Regardless, the “re-discovery” made Mendelism an important but controversial theory. Its most vigorous promoter in Europe was William Bateson, who coined the terms “genetics” and “allele” to describe many of its tenets. The model of heredity was contested by other biologists because it implied that heredity was discontinuous, in opposition to the apparently continuous variation observable for many traits. Many biologists also dismissed the theory because they were not sure it would apply to all species. However, later work by biologists and statisticians such as Ronald Fisher showed that if multiple Mendelian factors were involved in the expression of an individual trait, they could produce the diverse results observed, and thus showed that Mendelian genetics is compatible with natural selection. Thomas Hunt Morgan and his assistants later integrated Mendel’s theoretical model with the chromosome theory of inheritance, in which the chromosomes of cells were thought to hold the actual hereditary material, and created what is now known as classical genetics, a highly successful foundation which eventually cemented Mendel’s place in history.
Important information for writing discussion questions and participation
Welcome to class
Hello class and welcome to the class and I will be your instructor for this course. This is a -week course and requires a lot of time commitment, organization, and a high level of dedication. Please use the class syllabus to guide you through all the assignments required for the course. I have also attached the classroom policies to this announcement to know your expectations for this course. Please review this document carefully and ask me any questions if you do. You could email me at any time or send me a message via the “message” icon in halo if you need to contact me. I check my email regularly, so you should get a response within 24 hours. If you have not heard from me within 24 hours and need to contact me urgently, please send a follow up text to
I strongly encourage that you do not wait until the very last minute to complete your assignments. Your assignments in weeks 4 and 5 require early planning as you would need to present a teaching plan and interview a community health provider. I advise you look at the requirements for these assignments at the beginning of the course and plan accordingly. I have posted the YouTube link that explains all the class assignments in detail. It is required that you watch this 32-minute video as the assignments from week 3 through 5 require that you follow the instructions to the letter to succeed. Failure to complete these assignments according to instructions might lead to a zero. After watching the video, please schedule a one-on-one with me to discuss your topic for your project by the second week of class. Use this link to schedule a 15-minute session. Please, call me at the time of your appointment on my number. Please note that I will NOT call you.
Please, be advised I do NOT accept any assignments by email. If you are having technical issues with uploading an assignment, contact the technical department and inform me of the issue. If you have any issues that would prevent you from getting your assignments to me by the deadline, please inform me to request a possible extension. Note that working fulltime or overtime is no excuse for late assignments. There is a 5%-point deduction for every day your assignment is late. This only applies to approved extensions. Late assignments will not be accepted.
If you think you would be needing accommodations due to any reasons, please contact the appropriate department to request accommodations.
Plagiarism is highly prohibited. Please ensure you are citing your sources correctly using APA 7th edition. All assignments including discussion posts should be formatted in APA with the appropriate spacing, font, margin, and indents. Any papers not well formatted would be returned back to you, hence, I advise you review APA formatting style. I have attached a sample paper in APA format and will also post sample discussion responses in subsequent announcements.
Your initial discussion post should be a minimum of 200 words and response posts should be a minimum of 150 words. Be advised that I grade based on quality and not necessarily the number of words you post. A minimum of TWO references should be used for your initial post. For your response post, you do not need references as personal experiences would count as response posts. If you however cite anything from the literature for your response post, it is required that you cite your reference. You should include a minimum of THREE references for papers in this course. Please note that references should be no more than 5 years old except recommended as a resource for the class. Furthermore, for each discussion board question, you need ONE initial substantive response and TWO substantive responses to either your classmates or your instructor for a total of THREE responses. There are TWO discussion questions each week, hence, you need a total minimum of SIX discussion posts for each week. I usually post a discussion question each week. You could also respond to these as it would count towards your required SIX discussion posts for the week.
I understand this is a lot of information to cover in 5 weeks, however, the Bible says in Philippians 4:13 that we can do all things through Christ that strengthens us. Even in times like this, we are encouraged by God’s word that we have that ability in us to succeed with His strength. I pray that each and every one of you receives strength for this course and life generally as we navigate through this pandemic that is shaking our world today. Relax and enjoy the course!
