| pubmed-article:14703073 | pubmed:abstractText | A chicken bacterial artificial chromosome (BAC) library consisting of 138,240 clones was constructed in vector pBeloBAC11 with genomic DNA isolated from female white-silk chicken. An average insert size of 118 kb was estimated from 452 randomly isolated clones, which indicate the library to be approximate 13.34-fold genome coverage. For the demonstration of the probability to pick out any unique genes or DNA markers from the library, 8 single-copy genes were screened out and the positive clones were yielded between 2 and 15 with an average of 11.125, in agreement with the estimated high genomic coverage of this library. Positive superpools were obtained for 40 microsatellite markers selected from different regions of chicken genome. The number of positive superpools for each marker varies from 1 to 15 with an average of 9.475. | lld:pubmed |
