Higher levels of apoptosis in the absence of <i>Dmxl2</i> in testes from seven-week-old animals.

(A) Immunohistochemistry was used to detect cCasp-3 (brown) in control and dcKO testes. (B) The cCasp-3-positive cells were counted in each genotype, and the results are expressed per mm2 of seminiferous tubules. Asterisks indicate statistical significance (pValue = 0.028).
