By there DNA. When when x and y have sex they send there gene into the offspring
The answer is Dr Alec Jeffreys. <span>The genetic fingerprint and DNA profile are used by forensic science to help the police in their research work. The same technique has proved very useful in resolving litigation about paternity, for the identification of human remains in armed conflicts and for the identification of the corpses of historical figures.</span>
Answer
Your lower intestine of your body
Degeneracy
Degeneracy simply means that most of the amino acids produced during protein synthesis from DNA is coded by more than one codon. A codon is a sequence of 3 <span>nucleotides that codes for a specific amino acid.
Because more than 1 codon can produce the same amino acid, the chances of having the synthesis of proteins affected by mutations (i.e. point mutations) is decreased. For example, if the codon with the nucleotide series GAA, which codes for the amino acid glutamate, becomes the codon GAG, the codon will still produce glutamate because the code is degenerate. </span>
Fossils should be your answer
Fossils usually are bones, as bones are strong, and can last for long amounts of time without breaking down.
hope this helps
