If sperm with x fertilizes ovum embryo will normally develop as female (xx structure) If sperm with y fertilizes ovum the embryo will normally develop as male (xy structure: after fertilization zygote divides repeatedly, few short weeks one cell becomes billions of cells. 3 weeks primitive heart begins to drive blood through embryotic blood stream. If the y is absent, ovaries begin to differentiate.
