These verses state that humans are created from a drop of fluid, which reflects the universal ancient observation that semen is involved in reproduction. It lacks explicitly precise biological detail about X or Y chromosomes. In fact, traditional Islamic sources explicitly contradict modern genetics regarding gender determination; several authentic Hadith (such as those in Sahih Muslim) attribute the gender of the baby to whichever partner's reproductive fluid 'prevails' or 'dominates' during conception. This dominating-fluid concept actually mirrors ancient Greek and Galenic medical theories of antiquity rather than modern chromosomal science.
