If daughters are repeatedly born in a family what would be scientifically wrong to blame?

Answer and explanation

Correct answer: Only the mother

The governing concept is that the mother normally contributes X through every egg, while the father’s sperm contributes either X or Y. An XX combination results when an X-bearing sperm fertilises the egg, and an XY combination results when a Y-bearing sperm does so. Therefore, repeatedly having daughters is not scientifically the mother’s fault. Option A is correct; the other options refer to biological factors that should be understood, not unfairly blamed.
