Fine Mapping of a QTL for Fertility on BTA7 and Its Association With a CNV in the Israeli Holsteins.

A quantitative trait locus (QTL) affecting female fertility, scored as the inverse of the number of inseminations to conception, on Bos taurus chromosome 7 was detected by a daughter design analysis of the Israeli Holstein population (P < 0.0003).
