Solved in 2 steps
- What does it mean when an individual is found to be “homozygous” at a DNA profiling locus? They have three alleles at the locus They got different alleles from their mother and father They got the same alleles from their mother and father Their children got two alleles from them Their children got no alleles from themHow to find any evidence of cantamination or degradation of DNA in the DNA profiles you examined? how important is the detabase that is used to determine allele frequencies in DNA profiling casesJust like actual fingerprints, DNA fingerprints are unique to most individuals (other than identical twins). Today, most police departments in the United States use DNA fingerprints as a criminal investigation tool. What is another application of DNA fingerprints? O A. Identifyipg a person's personality traits O B. Identifying the father of a child O C. Identifying the sex of a future, not conceived offspring O D. Determining if a person has consumes genetically engineered plants
- An important application of DNA fingerprinting is relationship testing. Persons who are related genetically have some bands or peaks in common. The number they share depends on the closeness of their genetic relationship. For example, an offspring is expected to receive half of his or her minisatellites from one parent and the rest from the other. The diagram shown here schematically illustrates traditional DNA fingerprints of an offspring, mother, and two potential fathers. In paternity testing, the offspring’s DNA fingerprint is first compared with that of the mother. The bands that the offspring have in common with the mother are depicted in purple. The bands that are not similar between the offspring and the mother must have been inherited from the father. These bands are depicted in red. Which male could be the father?7. A burned body is found after a warehouse fire. You cannot obtain nuclear DNA suitable for testing, but you are able to obtain a sample of the person's mtDNA. What challenge will you encounter when trying to identify the person using mtDNA? Everyone has the same mtDNA so you won't be able to narrow identity down. mtDNA is most useful for information on traits like hair color so it won't narrow things down much. mtDNA only shows patrilineal lineage so it will only show the father's mtDNA. mtDNA is time consuming and expensive; not all labs have the capabilities to test this.How many individuals need to be genotyped in order to get an acceptable estimate of the rarity of alleles used for DNA profiling purposes? About 200 About 2,000 About 20,000 About 2,000,000 About 20,000,000
- Since DNA sequences are passed down from one generation to the next, people with closer familial relationship tend to have more of their DNA sequences in common. As a result, people who are more genetically related tend to share some similar patterns in their DNA fingerprinting. If you are comparing samples, which of the following can be determined with DNA fingerprinting? Group of answer choices? right chances Which fraternal twin each sample came from Which identical twin each sample is from If the samples are from people who are married If the samples came from mother and child asap pleaseI asked this question before but the solution was not correct and I'm really trying to figure out how to do this to get the correct answer. Please show work!DNA typing is used to compare evidence DNA (E) left at a crime scene to two suspects(S1 and S2). Suspect 1 is excluded by the evidence, but suspect 2 remains included. What isthe frequency of suspect 2's genotype if the allelic frequencies in the population are f(A1) =0.1, f(A2) = 0.2, and f(A3) = 0.7, and the population is at Hardy–Weinberg equilibrium?The answer is 0.49.The Human Genome Project has demonstrated that in humans of all races and nationalities approximately 99.9 percent of the sequence is the same, yet different individuals can be identified by DNA fingerprinting techniques. What is one primary variation in the human genome that can be used to distinguish different individuals? Briefly explain your answer.
- Humans only have a few eye colors and only four ABO-based blood types. The same can be said for almost all traits. Based on genetic traits, humans are very similair in their DNA. How then, can DNA tests definitively identify individuals? (What is being looked at/tested?)Could you also explain how DNA fingerprinting becomes a disadvantage as it pertains to relatives or twins?Can a change in a protein's shape affect a trait? Why or why not? O Yes, because proteins are the template to build DNA, which controls our traits O No, because shape is not related to function, so will not affect traits O No, because proteins are not related to traits, only DNA is O Yes, because shape determines function and traits come from proteins %23 (24
