Only the females.
Last year I had the DNA of my extended family analysed. Mainly we're, R1b's, H's, U5a's which are the most common haplogroups in Europe. My mother's haplogroup 'V' was a suprise...52% of the Skolt Sa'ami (northern Finland reindeer herders) have haplogroup 'V'.
My dad's mother (Mrs Smith) was/is related to 9,000 year old Cheddar Man.
