Karyotype Lab Write Up
Use your PowerPoint notes over, “Types of Mutations,” and your textbook to help you write your introduction. THIS MUST BE IN PARAGRAPH (not question-answer) FORM!!
- What are mutations and what causes them?
- What is the difference between somatic cell and gamete mutations? Can both be passed to offspring?
- Briefly describe the 4 types of chromosome mutations.
- What is a gene mutation?
- How does a point mutation occur?
- What is a frameshift mutation?
- What are karyotypes?
- How many chromosomes are in a normal human karyotype?
- What are the sex chromosomes?
- What sex chromosomes determine a male? a female?
- Give some examples of genetic mutations caused by nondisjunction.
- Write a statement explaining that karyotypes can help detect chromosomal mutations..
- In sentence form, list the materials from your lab sheet that are needed for this lab.
- In paragraph form, write the procedures for completing this karyotype lab.
- Each person or group will place their karyotype in your lab notebook on the page on which you start your results. Lab groups will turn in their notebooks together so the karyotype can be graded for each person
- Write out and answer the questions on the lab. Remember to NUMBER and UNDERLINE the question, but do NOT underline the answer. NOTE: HI-LITE THE ANSWER!
- Restate your hypothesis
- Tell what type of karyotype was made, the disorder if any, sex of the individual, chromosome number of karyotype)
- Explain how your karyotype shows the condition (normal, Down’s, Turner’s Syndrome, Klinefelter’s Syndrome, Cri-du-chat)
- Explain how your karyotype tells the sex of the individual
- Explain what chromosome mutation, if any, is present in your karyotype, whether it is an autosomal mutation or a mutation involving the sex chromosomes
- Use the internet or the library to find more about a person with this type of disorder (their appearance, how they look, etc.
