Summary Introduction
Introduction:
The method by which the DNA of a person is studied is called DNA profiling. This method is used for paternity testing to detect the biological parents of a child. The DNA profiling is also used for criminal investigations to detect the culprits.

- Observe the following DNA profile produced by STR analysis Ā Which child or children could be both this mother's and this father's children?

Can you tell which iswhich? C/AF = Child/Alleged father in one lane combined.arrow_forwardThe identity of Kim's biological father is unknown, but it is thought to be either Kevin or Thomas. To determine which of the two men it is, blood typing of all the persons involved was performed. Here are the results of the blood tests, including the phenotypes and possible genotypes of each person: Rachel (mother) Type AB; genotype IA, IB Kim (child) Type A; genotype is either IA, IA (if homozygous) or IA, i (if heterozygous) Kevin (alleged father #1) Type A; genotype is either IA,IA if homozygous or IA, i if heterozygous Thomas (alleged father #2) Type O; genotype is ii There are 2 DNA bands in the "fingerprint" of each person tested: mother, child, alleged father 1, and alleged father 2. Why are there two bands for each person and not three?arrow_forward

DNA interpretation did not exist at this time so the hospital traced the blood types of the family in order to determine if a mistake was made. The mother had Type A blood, the father had Type AB blood, and the baby had Type O blood.

- Lab technicians compile karyotypes and then use a specific notation to characterize the karyotype. This notation includes the total number of chromosomes, the sex chromosomes, and any extra or missing autosomal chromosomes. For example,Ā 47, XY, +18Ā indicates that the patient has 47 chromosomes, is a male, and has an extra autosomal chromosome 18.Ā 46, XXĀ is a female with a normal number of chromosomes.Ā 47, XXYĀ is a patient with an extra sex chromosome.
