The correct answer is option 3

Key Points

  • In the context of determining the percentage paternity of a child, HLA typing can be used because children inherit half of their HLA genes from their biological mother and half from their biological father.Hence option 3 is correct.
  • By comparing the HLA types of a child with those of their potential parents, it is possible to assess the likelihood of paternity.
  • A closer match in HLA types between the child and the alleged father indicates a higher probability of paternity.
