Question

investigators believe that an individual committed a murder; however, a week after the crime, the suspect died under suspicious circumstances. from which of the suspect’s family members could investigators collect dna that could help determine whether the suspect actually committed the first murder?
the suspect’s biological mother
the suspect’s biological father
the suspect’s adopted brother
the suspect’s biological daughter
any member of the suspect’s immediate biological family

Explanation:

Biological offspring inherit half their DNA from each biological parent. A suspect's biological daughter shares 50% of her DNA with the suspect, allowing for genetic comparison to link the suspect to crime scene evidence. Adopted family members share no biological DNA, and while other immediate biological family members share DNA, the daughter is a valid source as a direct biological relative. Among the options, the biological daughter is a correct choice (note: immediate biological family members like mother/father also share DNA, but the option "any member of the suspect's immediate biological family" is not the only correct single option here—however, the biological daughter is a specific valid choice from the options).

Answer:

the suspect's biological daughter
