Abstract From the Canadian patent

A molecular probe is provided for DNA specific for the male genome of bovines of the genera Bos and Bison. The molecular probe comprises a nucleic acid segment of: (i) a DNA segment of 49 base pairs length having the following 5'-3' nucleotide sequence, being designated by the name b.c.1.2: 5' 3', ATCAGTGCAGGGACCGAGATGTGCTCCAAGGAGTGTTTATCGGCTGCTT; or (ii) a DNA segment containing at least 11 consecutive nucleotides of the sequence; or (iii) any nucleic acid segment having a sequence homologous or complementary to the sequence of the abovementioned DNA segments. That probe hybridizes, with a sequence being repeated at least 2000 times in the male genome of the genera Bos and Bison. The probe …
