Question

D Question 1 1 pts Questions 1 through 8 all refer to the sample data and figure described here Because questions build on the results of preceding questions, you are encouraged to write out your calculations and results as you work through this assignment You assay 1000 diploid fruit flies for allelic and genotypic variation at the enzyme locus alcohol dehydrogenase (ADH)The assay consists of extracting protein from each fly and running it on anelectrophoreticgel. Some al ozymes proteln products of alleles) run faster on the gel whle others run slower, with each band Indicating a single, specific allele at the DNA level. The bands(show where the ADH allozyme alleles mlgrate to in thegel.You observe a total of six different banding patterns, labeled 1 through n the figure below. The vertical arrow on the left shows the direction of migration in the gel and pattern. (See Lecture Notes on Hardy-Weinberg equilibrium and F&H Box 6.2on p.189 for help with this type of Hardy-Weinberg prablem) # Observed refers to the observed number of flies showing a specific banding Banding pattern on ADI gel Ubserved: 19 Faster How many dirrerent ADH alleles are observed among the 1 000 fruit flies assayed? To help you in your work give these alleles labels e g,'F' tor tast, etc.). DQuestion 2 1pts Is inheritance at the ADH locus dominant or codominant?
