Fig. 1. Reaction norms for change in hematocrit from pre-breeding to the 1-egg
stage in the (A) unmanipulated (N=22), (B) estradiol-treatment
(N=23), (C) sham-treatment (N=26) and (D)
tamoxifen-treatment (N=18) trials. Plotted lines represent data from
individual females and grey filled circles represent the mean hematocrit
calculated at each stage.
