The women produces ova with ‘X’ chromosome and man produces sperms with X and Y chromosome. If the husband of the woman transfer X chromosome, then child will be a girl. On the other hand, if the husband transfer Y chromosome, the child will be a boy. In the case, the husband is always transferring X chromosome and hence, all the children are girl.
