1. A married couple has four girl children but no boys. This does not mean that the husband produces only X sperms. Explain why not?​

When sexually reproducing, a male produces both X and Y sperms, but the physical reproduction rates for male:female is 1:1 or 50% male 50% female. So if there are four daughters, that would just be a coincidence. If this helped you, could you give me brainliest, I'm trying to rank up :)
