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 please

- 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?Just 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 plantsWhat 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 them
- Many people are surprised to learn that,while each individual’s fingerprints are unique, the totalnumber of fingerprint ridges is highly heritable, about 90%heritability in many populations. What does high heritabilityof this trait mean?Below are two unrelated DNA paternity tests: one indicates the manis the father and the other shows he is not. Can you tell which iswhich? C/AF = Child/Alleged father in one lane combined.To understand this research, you must be familiar with some basic genetic terminology. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Not all terms will be used. dominant allele phenotype The possession of two different alleles of a particular gene is referred to as Reset Help A variation in a DNA sequence at one particular position is called a heterozygosity genotype recessive allele homozygosity single nucleotide polymorphism The appearance of the organism, its observable traits, are referred to as the A variant of a gene for which an individual must be homozygous in order for it to influence the appearance of the organism is a The set of alleles an organism has for a particular trait is the organism's Submit Request Answer

Line up the bands and illustrate vhich bands each baby inherited from its mother and from its father. Couple C M F Couple B Baby Baby Baby Couple A M F M F 1 3 Figure 1 DŇA fingerprint data obtained from three sets of infants and three sets of parents a. Identify which baby belongs to which set of parents. b. Explain why not all the bands in the mother's or father's profiles have counterpart in the baby's DNA profile. c. List other examples where DNA fingerprinting could be used to identify an individual. d. Explain why blood typing may not be a viable method of determining which baby belongs to which parent. e. Identify the largest DNA fragment on the gel. Identify the smallest DNA f. fragment on the gel. | | | | | || || | |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?)Which of the following individuals would you expect to share 25% of their DNA with you? Select all correct answers. Your aunt or uncle Your child Your first cousin Your grandparent Your parent Your sibling
- population is black in colour but about 1/4 of them are white. gene (B) that produces an enzyme that converts a pigment molecule to produce the Black colour. There are 2 alleles of this gene - the dominant B and the recessive b. DNA analysis shows that black individuals have either a BB or Bb genotype and that white individuals have a bb phenotype. However, you have discovered that a small percentage of White individuals have either a BB or Bb genotype. Explain two reasons that could explain this apparent anomaly. They have a BB or Bb genotype but a white phenotype.Monozygotic (identical) twins share all of the same DNA, yet have differences in appearance and behavior. Explain why this is, using the following terms correctly in your discussion: genotype, phenotype, multifactorial trait.You are working with a new species of spider in the lab. Wild type spiders have black legs and long mandibles. Mutants have black/brown striped legs and short mandibles. You perform a cross between wild type and mutant spiders. Your results : 5,502 wild type; 5,877 mutant; 69 black/brown striped, long mandibles; 52 black, short mandibles. What information does the recombination frequency tell you about the traits? (You will need to solve the RF first if you haven't done so in the other problem.) * A. Crossing over occurs frequently between the two traits. B. They are unlinked genes. C. They are located on separate chromosomes D. They are located very close together on the same chromosome.
