b) In the data table, record the tally for each phenotype in the row marked “Simulated Number.” c) In the row marked “Simulated Percentages,” convert the simulated numbers (out of 10) to simulated percentages (out of 100%). d) Compare the predicted values to the simulated values. How does the data confirm that black fur and black eyes are indeed dominant alleles? Step 3: Predict the Offspring of a Dihybrid Cross (BbEe × BbEe) Repeat step 1 using two mice from the F1 generation that are heterozygous for both fur color and eye color (BbEe). Step 4: Simulate the Cross in Step 3 Repeat step 2, except for two mice that are heterozygous for fur color and eye color (BbEe).
What was the independent variable and dependent variable of this experiment? - The independent variable: The blueberries. - The dependent variable: The performance of the mice in maze runing. 5. We are studying whether or not a

Genevieve 171L Honors 11/6/08 Characteristics of the Aldox Gene Introduction This experiment was conducted by using aldehyde oxidase (AO) to genetically characterize the aldox gene. It was hypothesized that the aldox gene is recessive and sex linked. Fruit flies (Drosophilia melanogaster) are genetically well known eukaryotic organisms that were used to investigate the inheritance of the aldox gene. To determine if AO is present, an enzyme spot test was used. The yellow color indicated that AO was present and active while blue color indicated AO is not present.
Fruit Flies as a mean of genetic study. BACKGROUND INFORMATION. In Mendelian genetics, one can study how heritable traits are passed from parents to their offspring. It gives us a way to predict the phenotypic and genotypic ratio of offspring. There are two kinds of alleles noticeable in genes: dominant and recessive alleles.
Lab Write-Up By Daniel Nunez 9/9/13 Title of lab: Pill bug behavior lab Background knowledge: Ethology is the study of animal behavior. Behavior is an animal’s response to sensory input and falls into two basic categories learned and innate (inherited) Problem statement/question: What will happen when pill bugs are placed in an area with one side wet and the other side completely dry? Hypothesis: The pill bugs will move towards the dry side. Test variable: The amount of bugs on each side. Outcome variable: The amount of pill bugs in each side.
RNA Lab Report If a codon is mutated, say from GGU to CGU, is the same amino acid specified?_______ Go to DNAi (www.dnai.org[->0]) > Code > Copying the Code. Start with the problem, and work through players, pieces of the puzzle, and putting it together. As you watch the video clips and animations, consider the data collected by the scientists involved. If a clue provides evidence for replication or transcription/translation, place an “X” beside the clue in the table, under “Supports replication” or “Supports transcription/translation”. If the clue does neither, or is not acceptable data, place an “X” in the “Does not support replication or transcription/translation” column.
Lab Report #12 Making a Genetically Modified Cell Answer the following questions about the results of the virtual lab activity. Record your answers in the boxes. Reference Use the following illustrations to help you identify the cell types from your lab. [pic] Activity 1 – Cell Maintenance Experiment 1 Record your results from Experiment 1 in the boxes below. Enter the information on the growth conditions, cell types, and cell density in the corresponding columns.
aa What is the genotype of person I3? Aa Test Cross Describe the test cross that a farmer would use to determine the genotype of an animal that shows a dominant trait. Use the following Punnett squares and the letters A and a to explain your answer. cross the animal with a recessive; if the animal is Aa crossed with aa – then ½ of the offspring will be recessive; if the animal is AA crossed with aa – all offspring will show the dominant trait. Mendel’s Laws Explain each of Mendel’s Laws and explain the experiments he used to determine these laws.
DON’T FORGET: As you work through these exercises, think of questions you may have and would want to test. Use these questions to come up with a hypothesis for your PopGen paper.
