Popis:	Productivity of F1 Booroola Merino (BM)×Rambouillet (R) ewes, ewes from the first and second backcrosses to R rams, and purebred R ewes were compared during the early stages of an introgression scheme to introduce the FecB allele into the R population. Fec genotype was estimated by counting corpora lutea during a laparoscopic examination of a ewe’s ovaries at 17 to 19 months of age. One copy of the FecB allele increased (P
