Only males have Y-DNA <ref>[http://isogg.org/wiki/Portal:Y-chromosome_DNA ISOGG Y-chromosome DNA]</ref>. A Y-DNA test <ref>[http://isogg.org/w/index.php?title=Y_chromosome_DNA_test&oldid=4956 ISOGG Wiki (http://www.isogg.org/wiki), Y chromosome DNA tests]</ref> provides two distinct signatures which identify all your direct-male ancestors and their direct-male descendants. This direct-male relationship (both ancestral and descendant) is sometimes called patrilineal and it means father to father for ancestral and father to son for descendant. The names of the two signatures are haplogroup and haplotype (see below). These signatures will be identical to or very nearly the same as all your direct-male relatives. <ref>[http://isogg.org/wiki/Y-DNA_STR_testing_chart <ref> [https://customercare.23andme.com/hc/en-us/articles/202906900-More-about-Haplogroups 23and Me More about Haplogroups]</ref>]</ref> <ref>[http://isogg.org/wiki/Y-DNA_SNP_testing_chart Y-DNA SNP testing chart]</ref>
