a young boy has been found, and police are trying to locate his family. they take a dna sample from him and begin collecting dna samples from families who have missing children. if police use dna samples only from the fathers, which type of dna technology can they use to identify the boys parent?\no y - chromosome analysis\no mtdna (mitochondrial dna) analysis\no vntrs (variable tandem repeats)\no pcr (polymerase chain reaction) analysis
Answer
Brief Explanations:
Y - chromosome is passed from father to son. So, Y - chromosome analysis can be used when only father's DNA samples are available to identify the boy's father. mtDNA is passed from mother to offspring, VNTRs and PCR are general DNA - analysis techniques not specific to father - son identification in this context.
Answer:
A. Y - chromosome analysis
