一种绵羊羊毛纤维长度相关的遗传标记及其应用
摘要：
本发明公开了一种绵羊羊毛纤维长度相关的遗传标记，所述遗传标记为绵羊KRTAP21-2基因的部分DNA序列；所述遗传标记的核苷酸序列如序列表中SEQ ID No：1-SEQ ID No：5所示；并提供了其扩增引物及应用。本发明的有益效果为：本发明提供了一种绵羊羊毛纤维长度相关的遗传标记，遗传标记位于KRTAP21-2上，可用于绵羊羊毛纤维长度的分子选育，KRTAP21-2共检测到5种等位基因，其中的等位基因E在编码区发生了氨基酸变异，其存在会引起平均纤维长度的降低，在育种时，若以提高平均纤维长度为目标，KRTAP21-2基因可作为其分子标记基因。
摘要（英）：

The invention discloses a genetic marker related to length of wool fibers of sheep. The genetic marker is a part of DNA sequence of a sheep KRTAP21-2 gene; and the nucleotide sequence of the genetic marker is as show in SEQ ID NO: 1-5 in a sequence table. Amplification primers and an application thereof are provided. The genetic marker disclosed by the invention has the beneficial effects that the genetic marker related to length of wool fibers of sheep is located on KRTAP21-2 and can be used for molecular breeding of length of wool fibers of sheep; the KRTAP21-2 detect five allele totally, wherein amino acid variation happens in the coding region of the allele E, so that the average fiber length will be reduced; and during breeding, the KRTAP21-2 gene can be used as a molecular marker gene if the genetic marker is targeted to improve the average fiber length.
