Progeny of crosses between Gcn5+/Δ and Gcn5flox(neo)/+ mice observed at the indicated time points. Observed numbers are close the to expected occurrence of 25% for each of the resulting genotypes.
One of these 53 embryos (1.9%) exhibited a neural tube defect (NTD).
One of these 16 embryos (6.3%) exhibited a neural tube defect (NTD).
