Abstract: Disclosed is an SNP marker related to wool traits of a fine-wool sheep, and a detection primer set, a detection method and use thereof, which belong to the technical field of molecular marker detection; the SNP marker is located at 133486008bp on sheep chromosome 3. There is an A/C base mutation at the site, which is significantly related to the wool traits of fine-wool sheep. The SNP marker of the present disclosure may be used in molecular marker assisted breeding of sheep. The molecular marker provided by the present disclosure is not limited by the age, sex, etc. of the sheep, may be used for fine-wool sheep breeding (even a sheep at birth may be accurately screened), and significantly promotes the breeding process of fine-wool sheep.

Abstract: The invention relates to a single nucleotide polymorphism (SNP) marker related to a Chinese horse short stature trait. The SNP molecular marker is located at the 501th position of a sequence shown in SEQ ID NO.1, polymorphism is G/A, and the SNP marker corresponds to base pair 18,205,998 on chromosome 8 in a horse. The SNP marker related to the Chinese horse short stature trait and use thereof provided by the present invention have the following advantages that: (1) the molecular marker is not restricted by the age, sex and the like of Chinese horses, is used in early breeding of the Chinese horses, performs accurate screening immediately at birth, and significantly promotes the breeding process of dominant pony varieties of the Chinese horse; (2) a method for detecting SNP of a Chinese horse TBX3 gene is accurate, reliable, and easy to operate.
