(A) Table summarizes the cross between Dgcr8delta/flox; Zp3-Cre or Dicerflox/flox; Zp3-Cre with wild-type males. For Dgcr8delta/flox; Zp3-Cre, each cross produces multiple litters, denoted by asterisk (*).
(B) Brood size from wild-type, Dgcr8delta/flox; Zp3-Cre (mutant), or Dgcr8delta/+ (het) mice. Each data point represents the number of pups per litter from wild-type (○), mutant (Δ), and het (◊) mothers. Brood size is reduced approximately 36% in the mutant compared to wild-type (p < 0.0001).
