In a cross between female flies expressing three X-linked recessive traits (scute bristles, sable body, and vermillion eyes) and wild-type males, all F1 generation females were wild-type while males expressed all three mutations. Analysis of over 1000 F2 generation offspring found deviations from expected numbers of double crossovers, suggesting the genes are arranged in a specific order along the X chromosome with some interference between crossovers.

2. In Drosophila, a cross was made between females - all expressing the three X -linked recessive
traits scute bristles (sc), sable body (s), and vermillion eyes (v) - and wile type males (P
generation). In the F 1 , all femaleswere wild type, while all the males expressed all three mutant
traits. The cross was carried to the F 2 generation, and 1000 offspring were counted, with the
results shown in the following table. No determination of sex was made in the data. ( 8 points)
(a) What are the genotypes of both the male and female parents in both the P and F 1
generations? (b) Determine the sequence of the three genes and the map distances between them.
(c) Are there more or fewer double crossovers than expected? (d) Calculate the coefficient of
coincidence. Does it represent positive or negative interference?

1. The invasive spotted lanternfly has made it to Vermont. It feeds on apples and maple trees and deposits honeydew that attracts other pests and encourages mold growth. The Vermont Agency of Agriculture is therefore very concerned. As a scientist working for the US Department of Agriculture, you're working to better understand the genetic bases of traits in this emerging crop pest species. You've identified three important recessive traits, cold tolerance ( t ), super sweet honeydew ( h ) , and rapid development (d) that could affect their ability to colonize Vermont. Limited cold tolerance ( T ) , regular honeydew ( H ) , and normal development ( D ) are dominant. You know these traits are linked to some degree based on your observations of inheritance patterns. You want to map these traits to the chromosome and determine the genetic distance between the loci. You cross purebreeding spotted lanternflies with cold tolerance, super sweet honeydew, and rapid development with purebreeding spotted lanternflies with limited cold tolerance, regular honeydew, and normal development. You then testcross the resulting F1 progeny and observe the following 1000 F2 progeny. A) Determine the gene order and fill in the progeny genotypes in the table above using the gene annotations noted above. (4 pts) Draw a genetic map indicating the gene order and genetic distance between all 3 gene pairs in units of map distance (or cM ); show your work for full credit. Note: You can calculate distance of outer loci by summing. ( 9 pts) B) Determine if the observed frequency of double crossovers is consistent with the expected frequency by calculating the interference value (I). Interpret the results as the % fewer double recombinants than expected. (4 pts) .

3. You are working on a forensics research project examining ancient remains recovered from a burial site in Norway, dating to 1000AD. You believe the skeletons may belong to the infamous King Kristoff and Queen Anna. Historical records state that this royal couple produced two children, Sven and Olenna, who then married each other in an attempt to strengthen the royal bloodline. They had a single son named Hanns, who went on to have one son named Wolf with his wife Talisa (otherwise unrelated to the family). Wolf never married or had children, but he spent his life with a male companion named Leif. The burial site contains 8 relatively well-preserved adult skeletons. You are able to extract enough DNA to successfully PCR seven microsatellite (STR) loci plus the amelogenin locus and want to determine whether the relationships of these skeletons match the legend of King Kristoff & Queen Anna. The table below includes data for the first six skeletons that have been analyzed. Answer the following questions and include a completed copy of Table 1 in your answers file. For the purpose of this assignment assume that parental alleles are transmitted faithfully without any new mutations. Table 1. Genotyping and Identification of skeletons at the ancient burial site.Table 1. Genotyping and Identification of skeletons at the ancient burial site. A. Draw the pedigree of this family, according to the historical records described above. Number the generations but identify all individuals by name rather than number. B. The genotyping results for the last two skeletons have just arrived. Use the capillary electrophoresis images shown below (Figures 13 ) to extract the genotypes and add them to the table. C. Use the DNA profiles and pedigree structure to determine who is who. Identify each skeleton by name in the table and provide a brief written rationale explaining how you arrived at this conclusion. D. In addition to the adults, the burial site also contains a fetus that appears to have been born at approximately 20 weeks gestation and did not survive. Due to the small amount of DNA available in the fetus, only 3 microsatellite loci could be genotyped. The fetus's DNA profile is provided below. Are you able to determine whether the parents were Kristoff and Anna; Sven and Olenna; or Hanns and Talisa? Explain. E. Hanns famously lost his hand in the battle of Clontarf. DNA from hand bones recovered at another burial site match Hanns's DNA profile, but you want to determine how common this DNA profile might have been in ancient times. Estimated allele frequencies for this population based on all recovered ancient DNA samples are provided below in Table 2. According to this information, what is the expected frequency of Hanns's DNA profile in this population? Is this result convincing that the hand belongs to Hanns?

How do i solve 5.8 and 5.9? 5) Epistatic cross: In this cross there are two genes (dihybrid cross) that are interacting where the presence of one will mask the other, this is known as an epistatic interaction. The genes involved in this cross are notched and apterous (wingless). The notched gene is sex-linked ( c chromosome) while apterous (wingless) is on an autosome. Both genes display dominance so heterozygotes will appear to have the wild phenotype. When apterous (wingless) is expressed (in a double recessive individual), we can not determine whether an individual has notched-wings or wild-type wings (Because it has no wings!). 5.1) Use the following symbols to write out the cross: Male: o, Use XnnY where " n " is either nw or nww: Female: + , Use XnnXn where " n " is either nw, or nwc+ On another chromosome: Apterous: wl Wild-type Apterous: wl + A genotype would include information about the sex and gene associated with the x-chromosome and a secondary gene that determines wings.
