QTL Experiment in Brief |
Animals: | Data for twinning rate from the North American Holstein breed were available through the National Association of Animal Breeders calving ease database. |
Breeds associated:
n/a
|
Design: | Information from granddaughters was used to estimate twinning rate PTA levels of sons. Sires, and sons of sires provided genotypic data. |
Analysis: | A total of 268 fluorescently labelled cattle primers were used for microsatellite marker genotyping. A linear regression approach was used for interval mapping through the QTL express program. |
Software: | Genescan, Tenotyper, Cri-Map, and QTL express |
