14. Why do dna testing companies eliminate matches under 7 cM
a) Matches under 7 cM may not provide substantial genealogical insight due to their high likelihood of being false positives.
b) Eliminating low-significance matches helps users focus on more relevant genetic relatives.
c) Matches above 7 cM are more likely to represent recent shared ancestry.
d) All of the above
