If you don't have an Azure subscription, create a free account before you begin. Deploy the ARM template to create a lab and VM.View the proportion of flies from your data that indicate crossover occurred (VG and BL flies) and multiple it by 100. How far apart are the alleles for black body and vestigial wings? The percentage of crossing over events is used to develop a map of chromosomes. How does crossing-over affect the observed outcomes? Explain why the observed flies do not match your prediction.ĥ. Show a punnett square or a visual representation of the alleles involved in this cross to make a prediction about the offspring.ģ. Choose a female from the offspring and mate it with a male that has vestigial wings and a black body. How many wild-type offspring are produced?Ģ. Cross a female VG, BL fly with a wild-type male. Vestigial wings (VG) and Black body color (BL) are located on chromosome 2.ġ. However, crossing-over can occur during meiosis and the alleles are switched. When two alleles are located on the same chromosome they are inherited together. Summarize your results and indicate whether your prediction is confirmed. Perform the cross and determine if your prediction is correct using statistical analysis. Show the punnett square to illustrate your reasoning.Ģ. Predict what the outcome of a cross between a wild-type fly and one with aristopedia. Wild-type flies do not carry the allele for aristopedia (aa).ġ.
Individuals with this trait must be heterozygous (Aa) because the homozygous condition (AA) is lethal. Summary: Explain how red/white eye color is inherited in fruit flies ( claim) and provide evidence from your data and chi-square statisticĪristapedia is a lethal allele that is also dominant. Perform the cross and use the statistical analysis tool to test your prediction.Ĥ. Explain your reasoning by showing a punnett squareģ. Predict what would happen if you crossed two of the offspring. How many of the offspring are males / red eyes?Ģ. Cross a white eyed male with a wild-type female. Summary: Explain how vestigial wings are inherited in fruit flies ( claim) and provide evidence from your data and chi-square statistic analysis.ġ. Place the expected numbers in the hypothesis field and click on "test your hypothesis." The program will do the chi square calculations.Ĭompare this to the chi square table to determine a goodness of fit.Ĩ. What proportion would have wild-type wings?ħ. If your hypothesis that VG is a recessive trait is correct, then you would expect what proportion of the F2 offspring to have vestigial wings? Under the Analyze tab, you can click on "Include a test hypothesis." In genetics, numbers are statistically analyzed. Design a male fly with vestigial wings and cross it with a wild-type femaleīased on these two crosses you probably have an idea about how vestigial wings are inherited.Ħ. Your next tasks will focus on analyzing single traits within flies to determine how they are inherited.Ģ. You may realize that choosing a lot of different types of flies make it difficult to analyze inheritance patterns. How many wild-type offspring were produced? (The button to "ignore sex" may make counting easier.) Use the analyze tab to get more details about the F2 offspring. Create a mutant fly with any number of variations and mate it with a wild-type fly. What are the body colors in fruit flies?Ħ. Regarding wing size, what is the difference between apterous and vestigial?ĥ. What are different eye colors in fruit flies? Circle the one that is wild-type.Ĥ. How is "aristapedia" different from wild-type?ģ. Geneticists use a shorthand labeling system, F = forked. Examine the different types of bristles seen in flies. A + sign is used to denote when a fly displays the wild-type characteristic.Įxamine the phenotypes available from the left side menu to answer the following questions.ġ. Recall that "wild-type" refers to the most common or typical form seen in the wild.
The image shown below shows a wild-type female fly (left) and a male fly. Students will make hypotheses for monohybrid, dihybridĪnd sex-linked traits and test their hypotheses by selecting fruit flies withĭifferent visible mutations, mating them, and analyzing the phenotypic ratios Apply the principles of Mendelian inheritance by experimentation with the fruitįly Drosophila melanogaster.
