A woman has only daughters.


A woman has only daughters. Analyse the situation genetically and provide a suitable, explanation.


A woman produces only one type of ova (22 + X) while her husband produces two types of sperms, gynosperms (22 + X) and androsperms (22 + Y)

in equal proportion. It is a chance that each time the woman conceived, only the gynosperm fertilised the egg so that only daughters were born.
