Some definitively, many not at all. Some more we may get exactly in future with further understanding of entire genome. And of course some can be affected by environment -- starting in utero and including epigenetic, nutritional, stresses, etc.Can anyone enlighten me about a few questions I have about the DNA source? Can the defense lawyer dismiss the evidence if there's no other sample to be tested by the defense team?
And - a biology question actually - all our characteristics as human are encoded on a DNA string right? So can you draw a picture of the murdered based of the genes found on that DNA? Like ethnicity, sex, hair color, eyes color, and more?
In fact jaw size, which we would assume to be kind of basic and entirely genetic, we know is impacted by eating habits and our hunter gatherer ancestors had larger jaws, fully or partially based on chewing more often (which is why modern people have wisdom teeth issues that our virtually genetically identical Paleolithic ancestors did not have).
As far as the DNA the state has the crime scene source. The matches to that woudl have progressed this way;
1) Investigators first used DNA and non DNA ancestry databases and were able to develop a suspect.
2) I believe they then they got a second DNA sample from Pennsylvania garbage. this almost certainly would be Kohberer and extremely close nuclear family males, excluding other males in the US (except his father to something like one in 10 or 100 million or on that order.) They probably used that to get extradition and warrants for house, car and Kohbergers person (including a cheek swab)
3) the cheek swab would probably exclude his father, and also serve to remove some of the attack the defense might make on the other DNA sources.
So the only weak point will be the DNA on the knife sheeth, and that may not be weak at all.
