Egg production of the daughters of mutant ‘restricted ovulator’ (R/O) sires. Individual egg production was monitored for either four or five PCR-genotyped daughters from each of 11 PCR-genotyped mutant (heterozygous) R/O sires for 331 d. During this period, the 27 wild-type (WT) daughters laid an average (±SD) of 255 ± 45 eggs, while the 26 R/O daughters averaged 6 ± 9 eggs laid.
