- The 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_forwardWhich of the following describes the pattern of sex chromosomes in this athlete?

- 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.arrow_forwardA mother has a child and needs to prove who the father is to get child support. Looking at the following DNA fingerprint, who is the father? How did you determine who was the father? Why is it important that ALL DNA samples are cut with the same enzyme?

This notation includes the total number of chromosomes, the sex chromosomes, and any extra or missing autosomal chromosomes. For example, 47, XY, +18 indicates that the patient has 47 chromosomes, is a male, and has an extra autosomal chromosome 18. 46, XX is a female with a normal number of chromosomes. 47, XXY is a patient with an extra sex chromosome.
