A person has cousins and second cousins on the side of one parent and cousins and second cousins on the side of the other.
Warren's DNA test would have been a mitrcochondrial one, as a female's chromosomes (the X one) is handed down through the female line. If it was Warren's mother's grandfather who was one-quarter Native American, then it wouldn't show in Warren's DNA, unless she got a male sibling or father to also take a DNA test for the Y-haplotype side.
AIUI Warren claims the DNA is in the female line (her mother) so it seems surprising that her DNA test supposedly reflects her one-quarter grandfather.
It's a red flag it's now the male side, when Warren claimed it was the female one.
Oh Dear, wrong again. You're not learning are you.

Warren's DNA was sequenced and analysed by a group led by Carlos Bustamante, a well-regarded Stanford University geneticist. Researchers studied a fraction - far less than 1/1,000th - of Ms Warren's DNA, and then compared it to the DNA of 148 people from Finland, Italy, Spain, China, Nigeria and North and South America. Additional comparison was done on 185 individuals from Utah and Great Britain.
As one might expect, the vast majority - 95 per cent - of Ms Warren's DNA indicated European ancestors. But five genetic segments were identified, with 99 per cent confidence, as being associated with Native American ancestry. The largest segment identified was on Chromosome 10.
"While the vast majority of the individual's ancestry is European, the results strongly support the existence of an unadmixed Native American ancestor in the individual's pedigree, likely in the range of 6-10 generations ago," the report said.

.... is using all the skill and knowledge accumulated over a lifetime of study to complete HIS TASK, you, some Nellie Nobody on an internet forum, are making stuff up out of whole cloth, in a field of study where you clearly have ZERO understanding, all so that you can try to avoid admitting that YOU ARE WRONG!!!!

Silly Green Monkey said... he/she is correct - especially the last sentence.
Here's a refresher course on DNA: Only sex-linked genes (those on the X chromosome itself) are handed down through the female line. When a male enters the line, he brings in one of his mother's X chromosomes, rather than a daughter receiving both one of her mother's X chromosomes and one of her father's mother's X chromosomes. There are 22 other chromosomes in a haploid cell which contain genetic information. These are also entirely separate from mitochondrial DNA, which is a different test. Stop digging, you're in the dark now. Making up stuff to support your position doesn't work when your audience knows your claims are ridiculous.
