of the flat pit and a long canal </span><span style="mso-bidi-font-family: "Times New Roman"">in
the animal polar region. </span><span style="mso-fareast-font-family: Calibri mso-bidi-font-family: "Times New Roman" mso-fareast-language: EN-US">The
micropyle region was not flat, micropyle was circular or oval in shape and the
micropyle canal was located in its center. Round or oval accessory pores were
also observed in the pit around of the micropylar canal. The surface of zona
radiata was smooth with a uniform distribution of almost round pores with lips.
