The first analyses used grandoffspring of wild-caught flies as sires and dams.
A total of 32 sires and 31 dams in 38 parental couples produced 151 litters.
In bulls, the efficiency of in vitro fertilization is highly variable amongst individual sires.
Their odds were improved greatly by siring offspring before the sister or in greater numbers.
The effective size depends on the variances and means of the numbers of times (l) the sires and the dams are bred in the herd.
151 progeny of sires used for detection of economic trait loci in dairy cattle.
In a granddaughter design, marker genotypes are available on elite sires and their sons and trait phenotypes are observed on daughters of sons.
The estimated substitution effects were large and similar for the four sires.
