Based on MS- LS3-1
- Can you make a model that shows how blue eyes originated? Can you include genes, chromosomes, traits, proteins, and organisms?
- Can you Include a Punnett Square to show how this trait could be passed on to the next generation?
- Note: can you include the drawing as question is suggested? can it be simpler for grade 8 level
Step by step
Solved in 3 steps
- Based on MS- LS3-1 Can you make a model that shows how blue eyes originated? Can you include genes, chromosomes, traits, proteins, and organisms? Can you Include a Punnett Square to show how this trait could be passed on to the next generation?A. Look at the pedigree, and DISREGARD individual II-8 for the moment. Is the pattern of inheritance of Unetan syndrome dominant or recessive? You may assume that the gene is FULLY-PENETRANT in this family. Please give two specific reasons that support your conclusion. B. Now, looking at BOTH the pedigree AND at the Southern blot, is this trait autosomal, X-linked, or Y-linked? Please give two specific reasons that support your conclusion. Once again, disregard II-8 for the moment. One of your two reasons must refer specifically to evidence present in the Southern blot. C. Define the gene alleles associated with Unetan syndrome. Your alleles MUST be consistent with the pattern of inheritance, AND your genetic notation must be consistent with that used throughout the course. Unetan syndrome allele: ________ Normal allele: ________PLEASE ANSWER THE FOLLOWING LETTERS: a,b,c, and d Examine the pedigree of the McGraw family shown below. Certain individuals in this family are affected by a brain condition that makes them more susceptible to vertigo. As a genetic counselor, you interview the family and draw DNA samples. You discover that the condition is caused by a mutation that changes the sequence 5’GCATTC3’ to 5’GAATTC3’ introducing an EcoRI cut site. You decide to amplify a 1200bp fragment from the DNA that spans this mutation and then digest it with EcoRI. You run the results on a gel next to a marker that shows bands at 2000bp, 1200bp, 900bp, 800bp, and 400bp. Some individuals from the pedigree are identified on the gel.
- Need help, please. What are the ratios for the progeny phenotype(s)?Why is karyotyping significant in understanding chromosomal abnormalities? Short essay only thanks please the main answerYou have already localized the genes to the same chromosome by deletion mapping, and now decide that the best way to accomplish the mapping is to conduct two simultaneous three-point testcross experiments. The genes you are investigating are as follows: N = round leaves, n = notched leaves; H = smooth stems, h = hairy stems; R = purple flowers, r = red flowers; B = grey seeds, b = black seeds; and Y = green pods, y = yellow pods. Earlier experiments you have done already established that gene B is in the middle of this gene cluster, so you design both three-point test crosses to include that gene. Cross #1 is designed as RrHhBb x rrhhbb while cross #2 is NnBbYy x nnbbyy. The results of both crosses are given in the table below. Based on the information given, determine the arrangement of these five genes including the position of each allele in the heterozygous fly and the distances between each pair of genes. (Hint: treat each experiment separately, knowing that gene B is in the…
- Q1: How many male and how many female descendants (individuals that did not join the family by marriage) does generation IV of Aldrich’s pedigree contain? Q2: What proportions of the male and female descendants in generation IV were affected by the disorder? Q3: Why did Aldrich hypothesize that the disease was X-linked?Compare and contrast the molecular and phenotypic features of Prader-Willi and Angelman syndromes.A RFLP is discovered that is linked to the gene for Duchenne’s muscular dystrophy (DMD). DMD is an X-linked, recessive trait. The RFLP is 2 map units from the gene for DMD. Consider the following pedigree and Southern blot using a probe that hybridizes to the RFLP. Which band/s is/are associated with DMD? What is the genotype for individuals 3 and 4? (Remember, this is an X linked disease, so use X’s and Y’s to denote). Individual 9 married a man who does NOT have muscular dystrophy, and she is pregnant. DMD is an X-linked trait. What is the probability for their child to have DMD? An amniocentesis is performed and it is determined that 9’s child in utero has only a 10 kb band that hybridizes to the same probe used above. What can you say about the child now?
- DNA sequencing of your own two β-globin genes (one from each of your two Chromosome 11s) reveals a mutation in one of the genes. given this information alone, should you worry about being a carrier of an inherited disease that could be passed on to your children? What other information would you like to have to assess your risk?What is a meaning of genetic linkage? How this test is used? Describe the meaning of SNP (single nucleotide polymorphisms) and genetic distance identification which is used in genetic analysis. Knowing that recombination events occur more or less at random along the length of chromosomes, in which case the recombination will occur more frequently between the genes during meiosis: if two genes are closer together two genes are far away from each other there is no impact based on location of two genes. What is a definition of DNA polymorphism and how can this be used for linkage studies? What is a definition of DNA polymorphism and how can this be used for linkage studies?How can you use this piece of information to help you explain to your friends what is the significance of mutations in the emergence of new genetic properties (alleles) that may result (or not) in new phenotypic characteristics? (Recall that not all SNPs affect phenotype.)
