Question

mother offspring male 1 male 2 male 3

c three men are claiming to be the father of the child of a rich heiress who died suddenly without leaving a will. they are all suing for custody of the child. a dna sample was collected from a toothbrush that was used by the heiress. blood samples were collected from each man and the baby. which man is the father of the child?

d jane was assaulted in an alley and is the victim of rape. a lab collected a sample of sperm that was found in the rape test conducted by the investigators. the police now have 3 suspects in custody. which of the suspects most likely raped jane?

e once again, two men were involved in a paternity suit brought by a woman against her estranged husband. the woman was seeking child support for her infant from her husband, but the husband accused the womans lover of being the biological father. unfortunately, blood typing was inconclusive: both men had the same blood type. so the judge ordered dna analysis. a sample of blood was taken from the mother, the baby, and both men. the results are shown below.

which of the men are most likely the father?

Explanation:

To solve these problems, we analyze the DNA or biological evidence provided in each case:

Problem C (Paternity Case with Three Men)

1. Understand the Goal: Determine which of the three men (Male 1, Male 2, Male 3) is the father of the child using DNA evidence.
2. Analyze the DNA Chart: Compare the DNA bands of the mother (Mother), the child (Offspring), and the three men (Male 1, Male 2, Male 3). The child's DNA should be a combination of the mother's and the father's DNA.
3. Compare Bands: For each DNA segment (row in the chart), check which male's DNA bands, when combined with the mother's, match the child's.

• The mother's DNA bands are in the "Mother" column, the child's in "Offspring", and the men's in "Male 1", "Male 2", "Male 3".
• By comparing each row, we find that the bands of Male 2 (in the "Male 2" column) complement the mother's bands to match the child's bands across most segments.

Problem D (Rape Case with Three Suspects)

1. Understand the Goal: Determine which of the three suspects (S1, S2, S3) raped Jane using the sperm sample (evidence) and the suspects' DNA.
2. Analyze the DNA Chart: Compare the DNA bands of the evidence (sperm sample) with the DNA of the three suspects (S1, S2, S3).
3. Compare Bands: For each DNA segment (row in the chart), check which suspect's DNA bands match the evidence.

• The evidence's DNA bands are in the "Evidence" column, and the suspects' in "S1", "S2", "S3".
• By comparing each row, we find that the bands of S2 (in the "S2" column) match the evidence's bands across most segments.

Problem E (Paternity Suit with Husband and Lover)

1. Understand the Goal: Determine whether the husband or the lover is the father of the infant using DNA evidence.
2. Analyze the DNA Chart: Compare the DNA bands of the mother (MOM), the baby (BABY), the lover (LOVER), and the husband (HUSBAND).
3. Compare Bands: For each DNA segment (rows 1–11), check which man's DNA bands, when combined with the mother's, match the baby's.

• The mother's DNA bands are in the "MOM" column, the baby's in "BABY", the lover's in "LOVER", and the husband's in "HUSBAND".
• By comparing each row, we find that the bands of the Husband (in the "HUSBAND" column) complement the mother's bands to match the baby's bands across most segments.

Final Answers:

• Problem C: The father of the child is Male 2.
• Problem D: The suspect who most likely raped Jane is S2.
• Problem E: The man most likely to be the father is the Husband.

Final Answers:

• Problem C: The father of the child is Male 2.
• Problem D: The suspect who most likely raped Jane is S2.
• Problem E: The man most likely to be the father is the Husband.
