Patent ID: 8790875

Claim:
A method for selectively breeding cattle, the method comprising superovulating a female animal, collecting eggs from said superovulated female, in vitro fertilizing said eggs from a suitable male animal, culturing said fertilized eggs into developing embryos, determining the identity of a nucleotide of the HSP gene of the developing embryos corresponding to at least one position selected from the group consisting of positions 1326, 1341, 1396, 1472 and 1480 of SEQ ID NO: 1, wherein the HSP gene comprises a nucleotide sequence of SEQ ID NO: 1, to identify a developing embryo that has guanine at position 1326, guanine at position 1341, adenosine at position 1396, cytosine at position 1472, or guanine at position 1480 of SEQ ID NO: 1, and planting into a suitable female the developing embryo the HSP gene of which has guanine at position 1326, guanine at position 1341, adenosine at position 1396, cytosine at position 1472, or guanine at position 1480 of SEQ ID NO: 1.
