You have purchased a kit from 23andMe to give your father for Father's Day. You instruct him to spit in the provided tube and mail it to the company. A week later, he receives his report. The report tells him that he shares haplotype blocks from people living on every continent (with the exception of Antarctica, which does not have an indigenous population). He is also told that about 2% of his genome is shared in common with Neanderthal DNA. He is surprised to hear this. Select the statement you might tell him that is most accurate:
There is strong evidence of interbreeding that occurred between humans and Neanderthals in non-African populations about 50,000 years ago.
There is strong evidence of interbreeding that occurred between humans and Neanderthals before humans migrated out of Africa about 75,000 years ago.
The process of using SNP-chips is error-prone, so the evidence of interbreeding between humans and Neanderthals is not reliable.
DNA from Neanderthals has never been successfully isolated.
