Reduced placental and embryonic weights in maternal Del^7AI heterozygotes at E15.5. Scatterplots of individual placental and embryonic weights at E15.5 for cohorts of wild type and Del^7AI heterozygous conceptuses obtained from reciprocal crosses. Bars show the average weight ± standard deviation for the given numbers of measurements (n). Results are shown following paternal (A) and maternal (B) transmission of the Del^7AI deletion. Differences in wild type and mutant means were evaluated using the two-tailed unpaired Student t test (p values). Asterisks mark mutant results significantly different from those of their wild type littermates (p<0.05).
